Durant cette Ignite, on a pu découvrir une fonctionnalité tres intéressante sur le stand de Jabra: Jabra Intelligent Call Transfer

Description:

In use with Skype for Business, Jabra Evolve can support call transfer from a Skype for Business desktop-based softphone call to a smartphone.  To transfer a call using the Evolve 40 and 80, simply un-plug the 3.5mm stereo jack stick from its control unit and the call will transfer to the user’s mobile phone.  Users can then insert the 3.5mm jack into the smartphone to continue the conversation or even continue the conversation using a Jabra Bluetooth™ headset.

The Jabra Intelligent Call Transfer will be available for Jabra Evolve 40 and 80 models exclusively in combination with the Skype for Business client and the latest Jabra Evolve firmware. Existing Jabra EVOLVE™ 40 and 80 models only require the new firmware upgrade and the latest Jabra Direct software to enable this feature, which will be released later this Fall 2015.

Microsoft a publié une mise a jour pour LRS:

About the SCEP feature in April 2015 update for Lync Room System:

This new feature supplements the existing Lync Room System (LRS) security design consisting of Windows Embedded firewall protection, AppLocker, and write filters. System administrators can easily enable Microsoft System Center Endpoint Protection (SCEP) on LRS by using an on/off toggle switch. The SCEP feature in LRS can run stand-alone, and does not require back-end server integration. Finally, LRS deployments in private network environments that have no direct Internet connection require some additional planning and preparation to enable SCEP malware signature updates through Windows Server Update Services (WSUS). Update from signatures that are stored in UNC file shares is not supported for the April 2015 LRS update. 

Microsoft vient de rendre disponible aux téléchargements le Microsoft Lync Room System Administrative Web Portal for Skype for Business Server 2015.

Description:

Microsoft Lync Room System (LRS) edition is a new Microsoft Lync unified communications client that has been optimized for Lync meetings in physical conference rooms. Install this web component on Skype for Business Server 2015 Front End servers in the pool where the Lync Room System accounts reside.

Une mise a jour d'outil sympathique est disponible sur les gallery technet: Skype for Business and Lync 2013 DDC - Detailed Design Calculator

Description:

DDC is a simple offline, Excel-based, low-level design calculator for Microsoft Skype for Business and Lync 2013 on-premises deployments. Fill in host names, IP addresses etc., and DDC will calculate DNS records, certificate names, firewall rules, deployment scripts and several other design elements to help speed-up your deployment.

DDC is a continuously evolving project and you should expect frequent updates with new features added over time. It is and will always be free.

Features

New in version 5.0.0:

New in version 5.0.0:

• Support for multiple SIP domains (up to 8), each with several configurable options (strict domain matching, SIP/XMPP federation, etc.)
• DNS tables reorganised for multiple domain support (records are sorted by domain).
• Added the ability to include/exclude external servers (Edge pool, Reverse Proxy) from the deployment
• Added the ability to choose AD or main SIP domain name for Pools and Web Services names (earlier DDC versions used primary SIP domain name by default and did not allow to change)
• Option to deploy 1 or 2 network cards on dedicated Mediation servers (separated internal and PSTN IP addresses). We have not included such option for collocated Mediation (not recommended)
• Option to use separate public IP addresses for external web-based applications (FE and Director pool web services, Office Web Apps)
• Support for Office Web Apps farms (up to 6 nodes)
• Additional scripts (setup accounts for synthetic transactions)
• Required empty input cells displayed in red

Other:
 

• Supports Standard and Enterprise pools (up to 12 nodes), with pure device-based load balancing (HLB) or a combination of DNS load balancing and device-based load balancing for web services (DNS LB);  
• Supports Edge, Director and Mediation pools (up to 12 nodes per role) with HLB or DNS LB;  
• Supports up to 4 PSTN gateways (can be media gateways, direct SIP trunks, etc.) with or without media bypass and configurable SIP over TCP or TLS, media ports, media bypass  
• Ability to specify custom media ports for clients and servers. DDC automatically applies consecutive non-overlapping ranges, and creates the appropriate commands on the Scripts sheet to apply these on to your deployment;  
• Calculates internal and external certificates CN and SAN; for the external certificate, it provides the option of separate or single certificate for Edge and Reverse proxy;
• Calculates DNS entries for internal and external zones. Further to that, DDC generates a script (in the Scripts sheet) which will automatically add the required records for both pinpoint or split-brain DNS.

  Calculates firewall rules for: 

• Internal firewalls (internal-facing DMZ); 
• External firewalls (external-facing DMZ);
• PSTN: The PSTN firewall sheet calculates custom rules for firewalls behind PSTN gateways, if any;
• Endpoints: the internal client Firewall sheet calculates custom rules for personal firewalls installed on clients, and rules required in scenarios with endpoints segregated by VLANs or other restrictions in place.

  Script section: new in version 4.x and still at an initial stage, but with plans to grow it over time. Currently it supports:

• DHCP: We have included a modified version of DhcpConfigScript.bat (http://technet.microsoft.com/en-us/library/gg412988(v=ocs.14).aspx), with the correct hexadecimal values automatically calculated and included, based on your design inputs; this removes the requirement to use dhcputil to generate the script and makes it ready to run on x86 and x64 Windows DHCP servers;
• DNS: Scripts to create necessary records based on dnscmd (with both pinpoint and split-brain, based on your selection);
• Office Web Apps: scripts to automate certificate request (through certutil), installation and web farm creation;
• Forward Proxy exceptions;
• QoS: PowerShell commands to configure custom port ranges;
• Setup accounts for synthetic transactions.

Microsoft vient de publier un KB concernant le comportement des invitations de réunion avec Google Chrome.
Un tres bel article décrivant la problématique est accessible ici: http://blogs.technet.com/b/scottstu/archive/2015/04/16/potential-impact-on-lync-and-skype-for-business-meeting-join-experience-when-google-chrome-is-the-default-browser.aspx

KB: 3057679

Lien: https://support.microsoft.com/en-us/kb/3057679

Description:

Consider the following scenario:

• Google Chrome is configured as your default browser.
• Your Google Chrome installation is upgraded to version 42 or a later version.
• You try to join a meeting by clicking a "Join Lync Meeting" or "Join Skype Meeting" link, and any one of the following criteria are true:
  • You click the link within any application other than Microsoft Outlook 2013.
  • The meeting organizer did not create the meeting by using the Outlook Lync or Skype for Business meeting plugin.
  • The meeting organizer is from another organization that has not configured the option to preserve the Transport Neutral Encapsulation Format (TNEF) for outgoing email messages. For more information, go to the following Outlook website:
    
    
    Manage TNEF Message Formatting with Remote Domains

In this scenario, when you click the "Join Lync Meeting" or "Join Skype Meeting" link, you expect the locally installed Lync or Skype for Business client to start. Instead, the default web browser starts and you are directed to the Lync Web App or Skype for Business Web App webpage. Then, you are prompted to install a plugin or you are joined to the meeting by using the web experience.

Cause:

This problem occurs because, by default, the updated version of Google Chrome deprecates and disables support for the Netscape Plugin API (NPAPI). NPAPI is currently used as part of the client detection process for the Lync or Skype for Business client when you join a meeting by clicking a link. When NPAPI is disabled, the webpage cannot determine whether you have the client installed.

Résolution:

To resolve this problem, use one of the following methods.

Option 1: Change the default browser

Set Internet Explorer or another supported browser as the user's default browser.

Option 2: Enable NPAPI

Enable NPAPI in the Chrome browser. To do this, follow these steps:

1. Enter the following URL into the Chrome address bar:
   
   
   Chrome://Flags/#enable-npapi
2. Click the Enable link to enable NPAPI support.
3. Restart the browser.
4. Click the meeting invitation link.
5. Enable the plugin for the meeting join domain by using the dialog box that follows the plugin warning message.
   
   Note This step is required for each unique meeting join domain, depending on the company that hosts the meeting.

Option 3: Set GPO settings

Use the Chrome ADMX template to set GPO settings that apply configurations to domain-joined computers. To do this, follow these steps:

1. Download the following Google Chrome GPO policy templates:
   
   
   Policy_templates.zip
2. Install the GPO policy templates by using the following directions:
   
   
   Scenario 2: Editing Domain-Based GPOs Using ADMX Files
3. Configure the "Computer Configuration\Administrative Templates\Google\Google Chrome\Specify a list of enabled plugins" setting by enabling the policy and specifying npapi as the value for enabled plugins.
4. Configure the "Computer Configuration\Administrative Templates\Google\Google Chrome\Content Settings\Allow plugins on these sites" setting by enabling the policy and by configuring the list of meeting join domain URLs that should be trusted.
   
   NoteThis list should contain the following items:
   • The meeting join URL of the user's organization
   • The URLs of any business partners that members of the user's organization frequently join in meetings
   • The default Lync and Skype for Business online meeting URL: https://meet.lync.com
