AudioCodes Element Management System (EMS):

Cisco a annoncé la disponibilité il y a quelques jours de la version 10.6 de Jabber pour Windows, Mac, IOS et Android.

Nouvelles fonctionnalités:

Chat and Presence

    Alert When Available - Set your client to notify you when a contact becomes available. Right-click over the user's name to select the Alert When Available option. You are notified the first time the user next becomes available. A message notification is displayed on the top-right corner of your screen to alert you that the user is available.

    Locations - Create, define, and display your location in your client for your contacts to see. Configure the Locations feature using the Location_Enabled parameter, and users can define their settings in the Options menu.

    Spell Check - For Windows 7 and Windows 8, you can define a default language from the Options menu. From the chat window with another user, you can personalize the language for chats with that user that is different from the default language in your client.

    Print Chat - You can print a conversation with a right-click from a chat window with another user or by pressing CTRL + P. You can also highlight a portion of the text to print it.

    AutoSave Chat - From the Options menu, you can automatically save chats to your computer when you close a chat window. Once the chats are saved to your computer, search the chat files or use your Windows file search capability to search the chat files. You can save peer-to-peer and group chat conversations. This feature is off by default.

    Client Behavior at Start Up - By default, the client opens in a minimized state. However, you can configure the client to open in the same state that it was in when you last closed it. For example, if you last exited the client with the Jabber window open, then the next time you start Jabber, the window is opened. You set the HonourLastWindowState parameter to true. The option to Start Cisco Jabber when my computer starts must be enabled by the user for the parameter to take effect.

    Remove Group Chat Participants - The person who starts a group chat can now also remove group chat participants. Removed chat participants can be re-invited to the chat room at any time.

    Conversation Tab Reordering - You can drag and drop any kind of tab in your conversation window to put them in your preferred order. You can drag and drop tabs from person to person chat, group chat, and persistent chat room conversations. You can also drag and drop tabs from persistent chat room searches and filters, and all types of call tabs for audio and video.

    Conversation Tab Switching Shortcut - You can move between chat tabs by using CTRL+TAB keyboard navigation, or use CTRL+SHIFT+TAB to move up and down between tabs for each conversation.

    Chat Security Labels - Label chats with security labels are now available, such as "secret" or "top secret", or your company can create its own labels. Compliant with the XEP-256 standard.

    Passwords for Persistent Chat Rooms (on-premises deployments only) - Persistent chat room administrators can restrict access to rooms by adding passwords to them.

    Save Chat History to Outlook Folder - Enable saving chat history automatically in a Microsoft Outlook folder. This feature is off by default. Prerequisites: Microsoft Exchange 2010 or 2013.

Sharing

    Share Menu - A new menu is available from chat windows to share your screen and start instant WebEx meetings. To access these options, select the More button from the conversation window.

    Size Limit for File Transfers - Define a file size limit for Cisco Jabber users when transferring files.

    File Transfer enhancements (on-premises deployments only, prerequisite: Cisco Unified Communications Manager 10.5(2) ) - In addition to standard file transfer between peers, you can now transfer files in group chats or persistent chat rooms. You can also use this feature to enable file transfer compliance, where you can manage screen captures and file transfers to restrict who can send and receive files, and keep a history of the file transfer and screen captures for auditing purposes.

Voice and Video

    Do Not Disturb - Call alerts and ringers are suppressed when your presence is Do Not Disturb, or in any red presence state. If you receive a call while in Do Not Disturb, you still see a missed call notification on your client. However, if you are using a headset with its own ringer, then the call rings is not suppressed on the headset. Both administrators and users can change settings for this feature.

    Call Notifications on Other Device - For users who do not want to interrupt their work to answer the phone, you can now disable incoming call alerts, which requires the call to be answered from a desk phone or a headset.

    Mute Before Answer - When you are joining a call, you can now mute your phone before you connect to the call.

    Audio Device Selection - You can select your preferred headset or other audio device directly from chat windows. A new option allows you to open audio options in the Jabber client, and select your microphone, headset, and ringer preferences.

    Ring on All Devices - You can hear incoming Jabber calls and alerts on your computer speakers and all connected devices. Even if your headphones are plugged in, when you receive a Jabber phone call or IM alert, the sound is played in both your headset and through your computer speakers. This feature is enabled by default, but users can change their ringer and alert preferences in the Audio tab of the Options menu.

    Call Stats - When on a call, users can now view information about the active call from their File menu, under View > Show call statistics.

Japanese Language

    This release includes improved Japanese localization.

User Management

    Single Sign On for Expressway for Mobile and Remote Access - You can now use SAML Single Sign On when connecting to the client from outside the corporate firewall on the Expressway for Mobile and Remote Access. Prerequisite: Cisco Expressway VCS-C or VCS-E 8.5(2).

    Mandatory Upgrade Support - You can now enable the client to require users to upgrade their client. To set mandatory upgrades for on-premises deployments, you set the Mandatory parameter in the upgrade .xml file to true. If you do not define mandatory upgrades, or you set it to false, then users can choose to install the update. If you set the mandatory parameter to true, then users can only select to install the update or exit the client. This feature is supported in Cisco Jabber for Windows 10.5(2) and later.

    Flexible Jabber ID - When setting up Jabber, the Jabber ID (which identifies the Jabber user) can be mapped to the Directory URI field on Cisco Unified Communications Manager. This ID allows Jabber to identify the Jabber user by their AD mail attribute or their AD msRTCSIP-primaryuseraddress attribute. A user can log into Jabber with their sAMAccountName attribute, while the Jabber ID is mapped to the Directory URI field. For more information, see the ID Address Scheme section in the Cisco Jabber 10.6 Deployment and Installation Guide.

    Multiple Presence Domains - Also known as Multiple IM Address Domains, Jabber can be deployed into an infrastructure where users are organized into more than one domain, or into domains with subdomains.

US Federal Government Requirements

    FIPS 140-2 - You can use Cisco Jabber for Windows in compliance with FIPS (Federal Information Processing Standard, Publication 140-2) to ensure compliance with the standards for information security and encryption. When you set your Operating System to run in FIPS mode, Jabber detects FIPS mode and also runs in it. For more information, see the Security chapter in the Cisco Jabber 10.6 Planning Guide

Suite à l'annonce du support des appels vidéos entre Skype et Lync et temporairement désactivé par la suite, Microsoft a annoncé officiellement espérer la réactivation de ce service a partir du 26 janvier 2015.

Les appels seront donc possible entre un client Lync et un Skype étant en version 7.1 ou supérieur (bientôt disponible).

Informations:

In December 2014, we announced the initial availability of video calling between Skype and Lync in a blog post on the Office Blogs website. In the weeks that followed that initial availability, we discovered several issues in the Skype consumer client versions that were enabled for video calling with Lync. These include at least one issue that could cause the Skype client to crash. Based on the severity of the issues, we disabled video calling for most Skype consumer users while we work on fixing the underlying issues.

Specifically, we're advising the following:

• As of January 20, 2015, video calling between Skype and Lync is disabled for most versions of the Skype consumer client. This is because of issues that were discovered that could cause the Skype Windows desktop client to crash in some cases.
• We're actively working on an updated Skype Windows desktop client, and we expect to release this on the Skype download page in the coming weeks.
• We will provide an updated message in the admin center when the work on this new client is completed.
• After we release a new Skype Windows desktop client, it takes several weeks until most of the end-users have upgraded and are enabled. During this interim period, Lync customers who want to test the new client's capabilities can instruct participants to manually download the new client from the Skype download page.

FAQ:

Q1: When and how will we re-enable video calling between Skype and Lync?
A1: We expect to re-enable this functionality no later than the week of January 26, 2015, when we release a new Skype Windows desktop client.

Q2: Regarding Q1, video calling with Lync will be re-enabled by using a new Skype Windows desktop client. How can I check whether I have the correct client?
A2: We will re-enable video calling with Lync or Skype Windows desktop client versions 7.1.xx.xxx and later versions. You can check the Skype version number by following the instructions at What version of Skype am I using on my computer?

Petit bug/irritant de la semaine (un parmi d'autres).

Contexte:

Intégration directe entre une ferme Lync Serveur 2013 et deux Avaya Session Manager 6.3.

Problème:

Lors d'un appel sortant depuis un endpoint Lync vers un opérateur spécifique (Telus pour ne pas le citer) via l'environnement Avaya, le numéro appelant apparait en "anonymous". Des appels vers l'ensemble des autres opérateurs ne présentent pas cet irritant.

Une trace côté Avaya me permet d'identifier le problème:

Solution:

C'est la première fois que je suis obligé d'activer cette option dans une intégration, la résolution consiste a cocher l’option « Enable forward P-Asserted-Identity data » au niveau des jonctions avec les deux Avaya session manager :

Résumé de l'option:

Plantronics propose sur son site un tool plutôt sympathique: Plantronics Aware for Lync 2013

Description:

Plantronics Aware for Lync 2013 is an application that provides enhanced presence capabilities for Microsoft Lync 2013 when used with Plantronics Hub for Windows software and Plantronics headsets. Features include changing Lync 2013 presence status to IN A CALL when you are on a mobile, desk phone or another softphone call using a supported Plantronics headset. Earlier versions of Microsoft Lync and Office Communicator do not require this application.

Prérequis:

- Plantronics Hub for Windows version 3.0 or higher
- Microsoft .NET Framework 4.0 or later (will be installed automatically if not present)
- Microsoft Lync 2013

Exemple de fonctionnalités:

- On a mobile phone call:
If you are using a multi-interface Plantronics headset that can connect or pair with multiple devices, e.g., a mobile phone as well as your PC for softphone calls, this feature will automatically set Microsoft Lync 2013 presence status to IN A CALL* when you are on a mobile call.
- On a deskphone call
If you are using a multi-interface Plantronics headset that can connect or pair with multiple devices, e.g., your deskphone as well as your PC for softphone calls, this feature will automatically set Microsoft Lync 2013 presence status to IN A CALL* when you are on a call using your deskphone.
- On another Softphone call
If you use other softphones in addition to Microsoft Lync 2013, this feature will automatically set Microsoft Lync 2013 presence status to IN A CALL* when you are on a call using the other softphone. This will happen whether or not you are wearing any headset.
- Escalate IM to Voice
This feature allows an IM session to be automatically escalated to a phone call when the user engaged in an active Lync IM session simply puts on their Plantronics headset. The IM session can only be with a single party. This features is only available for Plantronics devices equipped with the Plantronics Smart Sensors technology that can detect when the headset is worn.

Actuellement non compatible avec Office365.

Concernant le dernier article, ayant eu quelques messages concernant l'upload de la partie applicative vers le SFTP de PCD, voici un rapide guide.

1- Télécharger WinSCP

2- Connection au SFTP PCD:

Préciser:

- IP de PCD

- Username: adminsftp

- Passowrd: Mot de passe utilisé lors de l'installation du produit

3- Upload de votre iso vers PCD:

Uploader votre ISO vers le répertoire nécessaire en fonction de votre projet (migration, mise à jour,...).

Dans le cadre d'un projet intéressant a venir à très court terme, j'ai du plancher sur la capacité existante d'offrir, pendant la phase de mise en attente d'un appel, un flux live audio venant par exemple d'une station de radio ou télévision.

Les solutions ne sont pas nombreuses, en fait, qu'une fut retenue.

Avec les passerelles Sonus SBC 1000/2000, vous pouvez configurer ce type de fonctionnalité.

To connect a live audio source through an FXS port:

• Specify the live audio source using the Specifying a Live Audio Source procedure in Configuring the Media System.

Connecting an audio source for Music On Hold requires the use of an adapter between the Sonus SBC 1000/2000 RJ11 port and the source device (CD player, radio, iPod. MP3 player, personal computer, etc.). Common adapters include a 3.5mm connector on one end and an RJ11 on the other with an isolation transformer between the two.

Music On Hold volume is controlled from the audio source device (iPod, MP3 Player, etc.). The preferred volume level can be adjusted by listening to the stream, or by examining the RTP trace captured from the SIP call leg of the call. Use the receive gain settings on the FXS port to make any additional fine-tuning volume adjustments.

Source: _https://support.sonus.net/display/UXDOC41/Configuring+the+Sonus+SBC+1000-2000+for+Music+On+Hold

Pour les limitations:

1 seule source audio par passerelle

Impossible de centraliser cette fonctionnalité, 10 sites ayant leurs propres sorties terrestres locaux, 10 passerelles SBC1000/2000.

A l'écoute de toutes autres options possibles!

Dans le cadre de projet nécéssitant la récupération du matériel existant, la solution SPS (SIP Phone Support) de Audiocodes pour certain modèles spécifiques peut vous aider à atteindre ce but.

Pouvant être déployé sur un chassis médiant ou un environnement de virtualisation, SPS agit en tant que B2BUA entre votre téléphone et l'environnement Lync.

SPS supporte les modèles suivants avec la dernière release 3.0.6:

Il est possible d'avoir une architecture haute disponibilité:

La solution supporte:

• Architecture multi-site: réplication entre les serveurs SPS;
• mode direct: le flux audio entre deux téléphones SPS est en point à point;
• Lync media bypass;
• Lync Call Admission Control: appel entrant seulement;
• État de présence "ringing": Lorsqu'un téléphone sonne, le serveur SPS envoi un état "ringing" à l'environnement Lync;
• Auto Answer;
• P-Asserted-ID

La release 3.0.6 fixe les problèmes suivants:

• Handle leak in SPS switch
• Music-on-hold shuffle mode that played the same file
• Not allowing direct voicemail access for hosted voicemail over Edge
• Removed spaces in SPS configuration files that caused setup patch installation to fail
• Changed installation behavior so that if the patch fails, replace the old configuration file with the new configuration file.
• DTMF not working when connected to Office365 voicemail.
• Disconnect when calling destinations over edge server.
• Presence stuck on “Offline” if the Lync server fails and is restored
• Exception on unregister user endpoint
• Crash if CustomHeaders read from the database is null
• Media relay transfer to hosted voicemail
• SPS now does not send presence notification when it is up to date
• Wrong "away" publish for second device after first expires
• Wrong “phone in call” state if call is answered and disconnected in less than one second
• Added support for multiple ringing. If SPS receives multiple ringing or early media then now it will pass them all to IP Phone. This is required in case the destination has multiple devices,

En terme de fonctionnalités, vous pouvez trouver un récapitulatif ici:

Concernant le licensing, plusieurs options sont possibles. Par téléphone, pour 250 par exemple, le cout de récupération dans un environnement HA est de 44$ CAN.

L'exemple des 250 téléphones est dans un cadre de récupération de téléphones Cisco dans mon cas, la question ensuite d'investir dans la conservation de modèle 79XX EOL releve plus d'un aspect économique qu'autre chose.

Thomas Poett vient de partager un guide intéressant pour le troubleshooting Lync.

Le document de 130 pages est disponible ici: https://gallery.technet.microsoft.com/office/Skype-for-Business-and-7857597d

Description:

La mise à jour suivante permet de corriger les problèmes rencontrés avec Lync Web App pour les utilisateurs Google Chrome: 

http://microsofttouch.fr/default/b/christophe/archive/2015/01/03/microsoft-lync-server-2013-cumulative-update-du-31-d-233-cembre-2014-5-0-8308-866

Mais quel avenir de cette fonctionnalité avec Google Chrome?

On a eu la chance d'avoir de l'information en avance que je peux partager sans briser mon NDA:

Recent and upcoming Google changes to the Chrome browser affect the Lync Web App on both Mac and Windows platforms, and require us to make changes to Lync Server and Lync Online in order to deliver a great experience for Chrome users.  We have begun making these changes, and expect to complete them in the first quarter of 2015; in the meantime, when needed, we will provide users with manual work-around instructions as part of the meeting join experience.

For Mac users:  Google discontinued support in October for the 32 bit version of Chrome on Mac.  Because the existing Lync Web App works only in the 32 bit version of Chrome, Mac users must for now use either Safari or Firefox to join a Lync meeting.  When joining a Lync meeting, users with Chrome set as their default browser will see a message instructing them to copy the Lync meeting URL, open Safari or Firefox, and paste the meeting URL into the new browser window.  The Lync meeting will then begin.  We plan to remove this manual step for Chrome users by adding support for the 64 bit version of Chrome early in 2015.

For Windows users:  The most recent update to Lync Server 2013 (Cumulative Update 5.0.8308.857) provided manual work-around instructions to Windows users with the 32-bit version of Chrome set as their default browser, even though the 32-bit version of Chrome is still supported on Windows.  On 12/31/2014, we released a new update to Lync Server 2013 (Cumulative Update 5.0.8308.866) to remove the manual work-around instructions and to allow the Lync Web App to run in Chrome as it did previously.  We encourage administrators to apply Cumulative Update 5.0.8308.866 as soon as is practical to avoid the manual work-around.  We have already begun applying this update to Lync Online.

What’s next?  As noted above, we plan to add support for 64 bit Chrome on Mac early this year.  We are also working on solutions to minimize the impact on Chrome users with the planned deprecation of the so-called “Netscape Plug-In API”, or NPAPI, targeted by Google for April, 2015.
