Quels sont les nouveautés avec cette nouvelle version de Lync?

Pour la partie Lync Web App, les nouveautés sont nombreuses, c'était des questions qui revenaient souvent lors d'avant-vente, maintenant les fonctionnalités sont là, ce qui rends la solution lync pour la partie conférence vraiment complète et pouvant être comparé à Cisco Webex.

Qu'est-ce que Lync Web App ?

Lync Web App est la version navigateur de Lync 2013 qui permet aux personnes qui ne sont pas titulaires d'un compte Lync et qui n'ont pas installé le client Lync pour participer aux réunions Lync, avec un système d'exploitation Windows ou Macintosh. L'installation simple d'un plugin lorsque l'utilisateur rejoint la conférence permet d'accéder à l'ensemble des fonctionnalités. Seul l'utilisation de la roundtable n'est pas possible dans ce mode.

Un nouveau point d'accès est disponible, il s'agit du Cisco AP Aironet 1600.

Les nouveautés sont les suivantes:

• Cisco Client Link 2.0, qui permet d’optimiser l’utilisation et la portée du WiFi pour les clients traditionnels en 802.11abg, mais aussi pour les clients 802.11n n’utilisant qu’un flux d’émission (Spatial Stream), comme de nombreux smartphones,
• Cisco BandSelect, qui permet de mieux répartir les clients sur les deux bandes de fréquences 2,4GHz et 5GHz,
• Cisco VideoStream, qui contrôle la diffusion multicast des vidéo afin de prioritiser ces dernières et d’assurer une qualité vidéo inatteignable en WiFi standard,
• Cisco CleanAir Express, qui offre un niveau de detection et de classification des interférences permettant de configurer automatiquement les paramètres radio en évitant les interférences. (A noter que CleanAir Express sera activé par une version logicielle ultérieure).
• Cisco Mesh Indoor, permettant d’utiliser la technologie radio pour interconnecter les AP et atteindre des zones éloignées dans des déployement complexes

On se moment, j'enchaine les projets Microsoft Exchange UM 2010.

Lors de problématiques, avec Lync, il relativement facile de pouvoir faire des tests vers les fonctionnalités de messagerie vocale ou de réception automatisée, mais qu'en est-il avec une passerelle Audiocodes n'ayant pas de port FXS pour installer un téléphone analogique de test couplé à un système Avaya, Nortel,...?

Ayant actuellement un ticket ouvert chez Microsoft et Audiocodes pour un problème qui feras, je l'espère, l'objet d'un article très prochainement, je vais répertorier les solutions de troubleshooting proposées par Microsoft:

Exchange 2010 UM Troubleshooting Tool (Test-ExchangeUMCallFlow) pourra nous fournir plus de détails. Pourtant, puisque le succès de son exécution peut dépendre aussi d’autres facteurs, je préfère le garder en dernière option, après avoir confirmé que la configuration est bien complète.

Du au contexte bilingue du pays, je suis tombé sur un problème étant, malgré que le plan de numérotation Exchange 2010 UM est configuré en Français (Canadien), les messages vocaux sont reçus dans un emal en Anglais.

La problème était que les messages de voicemail que Exchange envoyé à l’usager qui n’avait pas de configuration régionale configuré dans Exchange était en anglais. 

Ceux-là qui avaient la configuration régionale dans Exchange configurer avaient les messages voicemail en français.

 La solution est la suivante, dans Exchange Powershell. On lance cette commande ::

Set-MailboxRegionalConfiguration <usager> -DateFormat yyyy-MM-dd -Language 'fr-CA' -TimeZone 'Eastern Standard Time' -Timeformat 'HH:mm'

On remplace <usager> avec le nom login de l’usager qui a les emails de Outlook Voice Accès en anglais. C’est le paramètre « Language » qui détermine la langue des courriels Outlook Voice Acces.

Voilà, toutes les balises et sujets envoyées par Outlook Voice Acces sont en français.

Merci au client pour cette solution.

De plus en plus, venant aussi du fait de concurrence les challengers habituels de la téléphonie IP, les clients souhaitent être en mesure de surveiller en temps réel l'activité des serveurs Microsoft Lync.

Par surveillance, il est entendu que je fais référence au recueil et l'affichage de toutes les données, des conditions relatives au fonctionnement et au comportement des équipements ainsi que desapplications incluant toutes les informations et les procédures requises pour faciliter
l'entretien et le bon fonctionnement des applications.

Pour une organisation ayant Solarwinds, il existe déjà des templates tout prêt pour effectuer ces tâches pour les rôles suivants:

Front-End: http://thwack.solarwinds.com/servlet/JiveServlet/downloadBody/155345-102-2-2778/Microsoft%20Lync%20Server%20(Front-End%20Role).apm-template

Mediation: http://thwack.solarwinds.com/servlet/JiveServlet/downloadBody/155347-102-2-2779/Microsoft%20Lync%20Server%20(Mediation%20Role).apm-template

Description: http://thwack.solarwinds.com/docs/DOC-155347

Edge: http://thwack.solarwinds.com/servlet/JiveServlet/downloadBody/155346-102-2-2777/Microsoft%20Lync%20Server%20(Edge%20Role).apm-template

Description: http://thwack.solarwinds.com/docs/DOC-155346

Front-End:

Service: Lync Server Audio Test Service

This component monitor returns the CPU and memory usage of the Lync Server Audio Test Service. This service offers users the ability to subjectively test the quality of a call before placing the call. The user checks the call quality by making a test call.

Service: Lync Server File Transfer Agent

This component monitor returns the CPU and memory usage of the Lync Server File Transfer Agent. The File Transfer Agent is responsible for replicating configuration settings with the Replica Replicator Agent that runs on every Lync Server.

Service: Lync Server Front-End

This component monitor returns the CPU and memory usage of the Front-End Lync Server. The Front-End Servers maintain transient information, such as logged-on state and control information for an IM, Web, or audio/video (A/V) conference.

Service: Lync Server IM Conferencing

This component monitor returns the CPU and memory usage of the Lync Server IM Conferencing. The IM Conferencing service is responsible for multiplexing the instant messages data feed from the leader to all participants in the session.

Service: Lync Server Master Replicator Agent

This component monitor returns the CPU and memory usage of the Lync Server Master Replicator Agent. This service is used by File Transfer Agent for replication configuration settings.

Service: Lync Server Replica Replicator Agent

This component monitor returns the CPU and memory usage of the Lync Server Replica Replicator Agent. This service is used by the File Transfer Agent for replication configuration settings.

SIP Peers: Connections Active

This component monitor returns the number of established connections that are currently active. A connection is considered established when peer credentials are verified (e.g. via MTLS), or the peer receives a 2xx response. You will need to baseline this counter by testing and monitoring the user load. This returned value should be less than 15,000 connections per Front-End.

SIP Peers: TLS Connections Active

This component monitor returns the number of established TLS connections that are currently active. A TLS connection is considered established when the peer certificate, and possibly the host name, are verified for a trust relationship. You will need to baseline this counter by testing and monitoring the user load.

SIP Peers: Sends Outstanding

This component monitor returns the number of messages that are currently present in the outgoing queues. If you receive error message 504, investigate the results from this counter. Doing so will indicate which servers are having problems. To do so, you will need to change the instance from _Total, to the server hostname. You can check this within perfmon.exe

SIP Peers: Average Outgoing Queue Delay

This component monitor returns the average time, in seconds, that messages have been delayed in outgoing queues. Check the Outgoing Queue Delay for delays in sending messages to other servers or clients that could be causing messages to be accumulated in the server. The server will drop client connections if it is in a throttle state and messages stay in the outgoing queue for more than 32 seconds.

SIP Peers: Flow-controlled Connections Dropped

This component monitor returns the total number of connections dropped because of excessive flow-control. You will need to baseline this counter by testing and monitoring the server's health. The returned value should be as low as possible.

SIP Peers: Average Flow-Control Delay

This component monitor returns the average delay, in seconds, in message processing when the socket is flow-controlled. You will need to baseline this counter by testing and monitoring the server's health. The returned value should be as low as possible.

SIP Peers: Incoming Requests/sec

This component monitor returns the rate of received requests, per second. You will need to baseline this counter by testing and monitoring the user load.

SIP Protocol: Incoming Messages/sec

This component monitor returns the rate of received messages, per second. You will need to baseline this counter by testing and monitoring the user load.

SIP Protocol: Events In Processing

This component monitor returns the number of SIP transactions, or dialog state change events, that are currently being processed. You will need to baseline this counter by testing and monitoring the user load.

SIP Responses: Local 500 Responses/sec

This component monitor returns the rate of 500 responses generated by the server, per second. This can indicate that there is a server component that is not functioning correctly.

SIP Responses: Local 503 Responses/sec

This component monitor returns the rate of 503 responses generated by the server, per second. The 503 code corresponds to the server being unavailable. On a healthy server, you should not receive this code at a steady rate. However, during ramp up, after a server has been brought back online, there may be some 503 responses. Once all users get back in and the server returns to a stable state, there should no longer be any 503 responses returned.

SIP Responses: Local 504 Responses/sec

This component monitor returns the rate of 504 responses generated by the server, per second. A few 504 responses to clients (for clients disconnecting abruptly) is to be expected, but this counter mainly indicates connectivity issues with other servers. It can indicate connection failures or delays connecting to remote servers.

SIP Load Management: Average Holding Time For Incoming Messages

This component monitor returns the average time that the server held the incoming messages currently being processed. This should usually be less than one second, on average, but it is normal to see short spikes of up to three seconds. The server will throttle new incoming messages after going above the high watermark and until the number of messages falls below the low watermark. The server starts rejecting new connections when the average holding time is greater than overload time of 15 seconds.

SIP Load Management: Address space usage

This component monitor returns the percentage of available address space currently in use by the server process. The returned value should be as low as possible.

SIP Load Management: Page file usage

This component monitor returns the percentage of available page file space currently in use by the server process. The returned value should be as low as possible.

IM Conferences: Active Conferences

This component monitor returns the number of active conferences. You will need to baseline this counter by testing and monitoring the user load.

IM Conferences: Connected Users

This component monitor returns the number of connected users in all conferences. You will need to baseline this counter by testing and monitoring the user load.

IM Conferences: Throttled Sip Connections

This component monitor returns the number of throttled Sip connections. If the value is greater than ten, it could indicate that Peer is not processing requests in a timely fashion. This can happen if the peer machine is overloaded. Peer is defined as the connected servers, adjacent Front-End servers, or MCUs in the same EE Pool. The same set of counters apply.

IM MCU Health And Performance: MCU Health State

This component monitor returns the current health of the MCU.

Possible values:
0 = Normal.
1 = Loaded.
2 = Full.
3 = Unavailable.

IM MCU Health And Performance: MCU Draining State

This component monitor returns the current draining status of the MCU.

Possible values:
0 = Not requesting to drain.
1 = Requesting to drain.
2 = Draining.

When a server is drained, it stops taking new connections and calls. These new connections and calls are routed through other servers in the pool. A server being drained allows its sessions on existing connections to continue until they naturally end. When all existing sessions have ended, the server is ready to be taken offline.

User Services - DBStore: Queue Latency (msec)

This component monitor returns the average time, in milliseconds, that a request is held in the database queue. This counter represents the time that a request spends in the queue of the Back-End Database Server. If the topology is healthy, this counter averages less than 100 ms. Occasional spikes are acceptable. The value will be higher on Front-End Servers that are located at the site opposite the location of the Back-End Database Servers. This value can increase if the Back-End Database Server is having performance problems or if network latency is too high. If the returned value is high, check both network latency and the health of the Back-End Database Server. Server health decreases as latency increases to 12 seconds, when server throttling begins.

User Services - DBStore: Sproc Latency (msec)

This component monitor returns the average time, in milliseconds, it takes to execute a stored procedure call. A healthy state is considered to be less than 100 ms. Server health decreases as latency increases to 12 seconds, when server throttling begins.

User Services - Https Transport: Number of failed connection attempts / Sec

This component monitor returns the rate of connection attempt failures, per second. You will need to baseline this counter by testing and monitoring the server's health.

 

Mediation:

Service: Lync Server Replica Replicator Agent

This component monitor returns the CPU and memory usage of the Lync Server Replica Replicator Agent. This service is used by the File Transfer Agent for replication configuration settings.

Outbound Calls: Current

This component monitor returns the total number of active calls going through the Mediation Server.

Outbound Calls: Active media bypass calls

This component monitor returns the total number of active calls going through Mediation Server that are in Media Bypass mode. Calls using Media Bypass use significantly fewer Mediation Server resources because the media is not flowing through the Mediation Server.

Inbound Calls: Current

This component monitor returns the number of inbound calls in progress.

Inbound Calls: Active media bypass calls

This component monitor returns the number of media bypass calls in progress.

Media Relay: Media Connectivity Check Failure

This component monitor returns the number of calls where media connectivity between the Mediation Server and the remote endpoints could not be established. The returned value should be as low as possible.

Health Indices: Load Call Failure Index

This component monitor returns the scaled index between zero and 100 that is related to all call failures due to Global Health Index as a heavy load.

Global Counters: Current audio channels with PSM quality reporting

This component monitor returns the total number of active channels that are having Phase Shift Modulation (PSM) quality reported. Calculating PSM quality has a processing overhead so this should be taken into account when measuring performance.

Total failed calls caused by unexpected interaction from the Proxy

This component monitor returns the number of calls that failed because of an unexpected response from the Front End Server. The returned value should be as low as possible.

Total failed calls caused by unexpected interaction from a gateway

This component monitor returns the number of calls that failed because of an unexpected response from a gateway peer. The returned value should be as low as possible.

Edge:

Service: Lync Server Replica Replicator Agent

This component monitor returns the CPU and memory usage of the Lync Server Replica Replicator Agent. This service is used by the File Transfer Agent for replication configuration settings.

SIP Peers: Connections Active

This component monitor returns the number of established connections that are currently active. A connection is considered established when peer credentials are verified (e.g. via MTLS), or the peer receives a 2xx response. You will need to baseline this counter by testing and monitoring the user load. This returned value should be less than 15,000 connections per Front-End.

SIP Peers: TLS Connections Active

This component monitor returns the number of established TLS connections that are currently active. A TLS connection is considered established when the peer certificate, and possibly the host name, are verified for a trust relationship. You will need to baseline this counter by testing and monitoring the user load.

SIP Peers: Average Outgoing Queue Delay

This component monitor returns the average time, in seconds, that messages have been delayed in outgoing queues. Check the Outgoing Queue Delay for delays in sending messages to other servers or clients that could be causing messages to be accumulated in the server. The server will drop client connections if it is in a throttle state and messages stay in the outgoing queue for more than 32 seconds.

SIP Peers: Incoming Requests/sec

This component monitor returns the rate of received requests, per second. You will need to baseline this counter by testing and monitoring the user load.

SIP Protocol: Incoming Messages/sec

This component monitor returns the rate of received messages, per second. You will need to baseline this counter by testing and monitoring the user load.

SIP Load Management: Average Holding Time For Incoming Messages

This component monitor returns the average time that the server held the incoming messages currently being processed. This should usually be less than one second, on average, but it is normal to see short spikes of up to three seconds. The server will throttle new incoming messages after going above the high benchmark and until the number of messages falls below the low benchmark. The server starts rejecting new connections when the average holding time is greater than overload time of 15 seconds.

SIP Access Edge Server: External Messages/sec With Internally Supported Domain

This component monitor returns the per-second rate of messages received at the external edge with an internally supported domain.

SIP Access Edge Server: External Messages/sec Received With Allowed Partner Server Domain

This component monitor returns the per-second rate of messages received at the external edge with an allowed partner server domain.

SIP Access Edge Server: External Messages/sec Received With a Configured Allowed Domain

This component monitor returns the per-second rate of messages received at the external edge with a configured allowed domain.

A/V Edge UDP: Active Relay Sessions - Authenticated

This component monitor returns the number of active relay sessions over UDP.

A/V Edge UDP: Active Relay Sessions - Allocated Port

This component monitor returns the number of active relay sessions with a UDP port allocation.

A/V Edge UDP: Active Relay Sessions - Data

This component monitor returns the number of active relay data sessions over UDP.

A/V Edge UDP: Allocated Port Pool Count

This component monitor returns the number of UDP ports available in the Allocated Port Pool. This monitor should be more than zero. If it reaches zero there is a resource issue.

A/V Edge UDP: Allocate Requests/sec

This component monitor returns the per-second rate of Allocate Requests over UDP. You will need to baseline this counter by testing and monitoring the user load.

A/V Edge UDP: Authentication Failures/sec

This component monitor returns the per-second rate of failed attempts to authenticate with the relay over UDP. The returned value should be as low as possible.

A/V Edge UDP: Allocate Requests Exceeding Port Limit

This component monitor returns the number of allocate requests over UDP that exceeded the port limit. If the value is greater than zero, this could indicate an attempt to misuse the port.

A/V Edge UDP: Packets Received/sec

This component monitor returns the number of packets, received per second, by the relay over UDP. You will need to baseline this counter by testing and monitoring the user load.

A/V Edge UDP: Packets Sent/sec

This component monitor returns the number of packets sent per second by the relay over UDP. You will need to baseline this counter by testing and monitoring the user load.

A/V Edge UDP: Average Data Packet Latency (milliseconds)

This component monitor returns the average latency for a valid data request over UDP in milliseconds. The returned value should be as low as possible.

A/V Edge UDP: Packets Dropped/sec

This component monitor returns the per-second rate of packets over UDP dropped by the relay. The returned value should be as low as possible.

This error occurs when an unexpectedly high rate of User Datagram Protocol (UDP) packets is received at the Media Relay (A/V Edge server)  causing some packets to be discarded. This could be the result of system overload or an indication of an attempt to misuse the MR.

To resolve this, check that the profile of network traffic to the MR is in line with expected usage. If the traffic exceeds 250 Mbps per interface, increase the Receive and Transmit buffer size on the associated network adapter network adapters to three times the default values.

If the cause is a general system overload, increase the capacity of the deployed MR function. A network level trace can be used to determine if there is an unusual amount of traffic originating from a single source. If the situation persists, enable tracing to check the network source of sessions exceeding the bandwidth limits to allow further troubleshooting of the cause.

A/V Edge TCP: Active Relay Sessions - Authenticated

This component monitor returns the number of active relay sessions over TCP.

A/V Edge TCP: Active Relay Sessions - Allocated Port

This component monitor returns the number of active relay sessions with a TCP port allocation.

A/V Edge TCP: Active Relay Sessions - Data

This component monitor returns the number of active relay data sessions over TCP.

A/V Edge TCP: Allocated Port Pool Count

A/V Edge TCP: Packets Received/sec

This component monitor returns the number of packets received per second by the relay over TCP. You will need to baseline this counter by testing and monitoring the user load.

A/V Edge TCP: Packets Sent/sec

This component monitor returns the number of packets sent per second by the relay over TCP. You will need to baseline this counter by testing and monitoring the user load.

A/V Edge TCP: Average Data Packet Latency (milliseconds)

This component monitor returns the average latency for a valid data request over TCP in milliseconds. The returned value should be as low as possible.

A/V Edge TCP: Packets Dropped/sec

This component monitor returns the per-second rate of packets over TCP dropped by the relay. The returned value should be as low as possible.

This error occurs when an unexpectedly high rate of User Datagram Protocol (UDP) packets is received at the Media Relay (A/V Edge server)  causing some packets to be discarded. This could be the result of system overload or an indication of an attempt to misuse the MR.

To resolve this, check that the profile of network traffic to the MR is in line with expected usage. If the traffic exceeds 250 Mbps per interface, increase the Receive and Transmit buffer size on the associated network adapter network adapters to three times the default values.

Merci à lui!

Bonne surprise ce matin, la version Lync Server 2013 est disponible au téléchargement!

On retrouve aussi Exchange 2013, Sharepoint 2013, Office 2013, Visio 2013....

Il arrive que des fois, lors d'une phase de coexistence Lync ocs, que l'on supprime un peu vite les anciennes stratégies.

Le résultat est le suivant lors de la phase de migration d'un utilisateur concerné par la legacy policy supprimée: Move-CsLegacyUser : All policies of type "DialPlan" are not migrated

Il est pas forcément pertinent de relancer la commande d'import des anciennes stratégies, on peut bypasser cela avec les options suivantes:

-ExcludeVoicePolicy -ExcludeDialPlan -ExcludeConferencingPolicy

De gros changement concernant les futurs certifications Lync Server 2013, le programme est maintenant le suivant:

Donc adieu aux titre de mcts et mctip, obligation de passer une certification purement OS avec le mcsa Windows Server 2012 ce qui est pour un quelqu'un des télécoms, pas forcément une bonne nouvelle.

Le processus MCSA Windows Server 2010 est le suivant, à noter que pour les MCTIP Lync Server 2010, il est heureusement possible de le valider en passant l'examen 417.

Les deux examens 336 et 337 devrait être disponible pour la mi-novembre 2012.

Bien penser à l'update SQL suite à l'application des cumulatives updates!

D'après "The Lync Team Blog" de Microsoft, le client Lync 2013 est finalisé en terme de développement.

Il devrait être disponible quelque part dans le 1ier trimestre 2013

We wanted to let all of our blog readers know that the engineering team has signed off on the Release to Manufacturing (RTM) build of Lync 2013, as-of today, October 11th, 2012! General availability is planned for the first quarter of 2013. Starting October 19, any customer purchasing Office 2010 in retail will receive the new Office for free upon availability. Customers will see a preview version of the new Office on Windows RT devices, beginning with the Windows 8 launch on October 26.

Lundi 8 octobre a eu lieu la grande messe Polycom "NASDAQ Strategy Day".

Ce fut une présentation vraiment intéressante des nouvelles technologies arrivant sur le marché, en tant que consultant UC, on est tout de suite conscient que ces produits vont fortement influencé le marché.

On y découvre la technologie "RealPresence CloudAXIS" :

CloudAxis is a Web-based application that lets the host of a call set up credentials to the services he or she subscribes to, creating a presence directory. To set up a conference call, the host drags the names of people to be called onto the screen and the software fires an instant message to them. The IM includes a secure Web link for the call.

Users only need a browser plug-in to participate. Up to 40 people can be on a conference call, which allows a shared desktop.

A piece of the CloudAxis suite called the Flexible Resource Broker deals with bandwidth, sets up resources and links to the RMX and DMA servers. An Access Director sets up the presence directory and enables firewall traversal.

“It gives as a host the capability to call out to anybody at anytime without firewall hassles,” 

Ce produit devrait être disponible pour la fin du 1ier trimestre 2013.

Datasheet: http://www.polycom.com/content/dam/polycom/www/documents/data-sheets/rp-cloudaxis-suite-ds-enus.pdf

Polycom devrait supporter le standard H.264 SVC pour beaucoup de ces produits par un update software, ce qui tombe bien puisque Lync 2013 aussi.

L'ensemble de la présentation est visible ici: http://www.polycom.com/company/features/video-collaboration-20121008-player.html

On y retrouve des informations sur les nouvelles technologies suivantes:

• Polycom RealPresence Collaboration Server 800s, Virtual Edition
• Polycom RealPresence Group Series 300
• Polycom RealPresence Mobile 2.0
• Polycom RealPresence Desktop for Windows and Mac

Actuellement, la documentation technique n'est pas trop fourni, mais je suis curieux de voir le futur couplage avec Microsoft Lync. A suivre!

Une série d’articles concernant le déploiement de Lync 2013 seront publiées très prochainement.

 

Commençons par les prérequis :

 

Au niveau hardware, on reste sur les mêmes préconisations, il faut prendre en compte les nouveaux points suivants qui auront des incidences sur le sizing:

 

-        La centralisation du rôle de Front-end et Audio/Vidéo sur le même serveur

-        La colocalisation de la passerelle XMPP

-        Les nouvelles fonctionnalités HD et multi-vue très consommateurs en ressources CPU

 

En phase Béta, les capacités annoncées pour l’instant sont les suivantes :

-        12 à 20 serveurs par pool

With the growing adoption of Unified Communications (UC), many people now rely on laptop PCs and other untethered computing devices as their primary phones. The service provided by IntelePeer and 911 Enable is ideal for organizations housed in corporate campuses or other facilities where Microsoft Lync users often take their devices with them. When the user places an emergency call, the companies’ technologies work together to seamlessly and automatically provide the caller’s location information to the 911 operator at the geographically appropriate Public Safety Answering Point (PSAP), ensuring that emergency personnel can quickly and accurately respond.

 “With the proliferation of Unified Communications across corporate campuses, it’s important to ensure that seamless E911 support is available regardless of the user’s device,” said Lev Deich, director, 911 Enable. “Our E911 offerings help organizations to comply with state and federal regulations and are qualified by Microsoft, giving customers who use Microsoft Lync with IntelePeer SIP Trunking a proven, high-quality solution that delivers peace of mind.”

J'ai étais récemment nommé et sélectionné par Microsoft en tant que Virtual Technology Specialist (V-TSP) pour Lync concernant la partie voix sur IP.
Les V-TSP Lync sont divisés en deux groupes, IM/présence et Voice, il n'y avait qu'une place au Québec apparement pour la seconde spécialisation, cela peut-être une belle expérience.

Le programme V-TSP?

The Microsoft Virtual Technology Specialist Program (VTSP) is a select group chosen from the elite in Microsoft’s partner community, whose focus is to augment Microsoft’s internal Technology Specialist team. Their primary role is to communicate the value of Microsoft Solutions to customers and to provide architectural guidance for Enterprise Integration solutions. The Microsoft VTSP program was designed to create a deeper relationship with Microsoft Partners, the Product Teams at Microsoft Corporate, and Regional Microsoft Offices, in order to provide highly skilled solution specialists to Microsoft customers. It is designed to enable a high performance team of partner-based resources to deliver pre-sale activities and resources to empower customers and help them meet their solution and integration needs.


Alors qu'est-ce que cela signifie pour moi? En tant que VTSP,  je vais avoir accès aux ressources, la documentation technique interne, l'accès VPN, un badge pour les locaux ainsi qu'une adresse e-mail microsoft.com.


Je suis vraiment heureux de faire partie du programme et de découvrir les nouvelles opportunités et défis que cela va amener!

J'ai eu l'opportunité d'implémenter  un nombre important d'environnement Lync Server 2010, que ce soit des entités n'ayant pas d'univers UC ou migrant depuis Office Communication Server 2007 R1 ou R2, Live Meeting était relativement peu utilisé pour diverses raisons (interface pas très friendly, pas si simple à appréhender,...), abandonner ce client pour Lync 2010 ne fut jamais un problème, au contraire même, la simplicité du client le rendant plus accessible.

Dans le cadre d'une migration OCS 2007 R1 vers Lync Server 2010, j'ai eu l'occasion de travailler récemment pour une organisation utilisant Live Meeting à grande échelle, pouvant aller jusqu'à 500 personnes dans une session (le serveur OCS 2007 R1 étant virtualisé et ayant 1gb de ram).

Il est vrai que si on regarde de plus près, la transition pour certaine fonctionnalité n'est pas si simple. Voici un tableau présentant les fonctions manquantes:

Certains points ne sont pas insurmontables, mais connaitre ces limitations est important.

Il est possible de visionner des vidéos très intéressantes concernant la nouvelle version Lync Server 2013 venant directement des sessions qui se sont déroulés au TechEd en Australie.

Les sujets et les vidéos associés sont répertoriés ici:

Lync 2013 Architecture (EXL314) – here

Lync 2013 Meeting Improvements (EXL316) - here

Lync 2013 Deployment (EXL321) – here

Lync 2013 Voice Improvements (EXL325) – here

Demystifying Integration of Lync to your Existing PABX (EXL231) – here

Lync 2013 and Enterprise Networking (EXL334) – here

Il arrive pour diverses raisons (migration et changement de domaine sip par exemple), que l'on doit jongler avec plusieurs domaines sip.

Ce qui peut causer cet pop-up sur certains postes clients:

Pour que l'utilisateur final ne soit pas déstabilisé par l'apparition de cette fenêtre, il faut modifier la valeur de Registre TrustModelData dans l'emplacement  "HKEY_CURRENT_USER\Software\Microsoft\Communicator\" et inclure le nom du pool.

Une chose intéressante depuis l'annonce en fin d'année dernière du firmware polycom permettant d'intégrer ces modèles avec Lync server, les modèles Polycom VVX500 IP et SpectraLink sont officiellement qualifiés pour Lync :

SpectraLink:

VVX500:

Je ne vais pas pouvoir faire de retour rapide sur ces deux modèles, récemment, j'ai plutôt privilégier des kirks que les spectralink sur un nouveau projet de migration téléphonique vers Lync vu le contexte du client, mais je ne manquerais pas de le faire à l'occasion
