2New Features

2.1 Cisco Jabber support on jamvee™ (for audio, video and content sharing)

Jamvee™ introduces support for inbound SIP IP audio, video and content sharing from any Cisco Jabber UCC endpoint deployed within a customer’s enterprise via supported SIP-call flows across a jamvee™ transport access method.

 2.2 Jamvee Audio On-Net Access via Global SIP Connect (GSC) Trunk

This jamvee transport access method provides an option for jamvee customers to connect their enterprise IPT/IP PBX platform to the jamvee service for “on-net” audio-only access to a jamvee conference. The user will dial a CUG number from within the enterprise voice network and that call will be routed via a standard Global SIP Connect (GSC) trunk between the customer’s network (PoD), into the TCL Global Voice Network and eventually to the jamvee conferencing platform within the GMX Cloud. This release introduces support for the end-to-end integration of the TCL ordering/provisioning/billing systems.

2.3 QoS Access from jamvee™ UC Client/Lync – UC Port (IP Transit)

This jamvee™ transport access method provides an option for jamvee™ customers to connect their “Internet-bound”, enterprise-deployed jamvee™ endpoints (e.g. jamvee™ UC Apps and federated Microsoft Lync clients) to a jamvee™ conference hosted on the TCL “GMX Cloud” using “UC Port/IZO Public” on the IP Transit network (AS6453 network with QoS as defined by the IZO Public service) with end-to-end QoS to the enterprise Point of Demarcation (PoD). This feature requires the end-to-end integration of the TCL ordering/provisioning/billing systems.

2.4 QoS Access from jamvee UC desktop and web Client/VC endpoints via vUTM

The MPLS vUTM transport access method solution supports jamvee™ UC traffic from enterprise deployments of the following endpoints:

  • Jamvee UC Desktop/Mobile/WebRTC App traffic origination from the enterprise network,
  • Cisco Jabber UC SIP traffic from the enterprise to jamvee, and
  • H.323/SIP VC/TP Endpoint Traffic

2.5 Skype Consumer Audio and Web support on jamvee™

Jamvee™ UC now supports audio and web functionality for the Skype consumer app (Note: Skype Video is only provided on a “best effort” basis in this release). For more details and configuration notes please check the FAQ section on the portal.

2.6 Enhanced User Interface support for jamvee™ iOS client

The user interface for the jamvee™ iOS app has been upgraded to the same version released last quarter for PC and Mac devices, providing a more consistent experience for the user irrespective of the device (laptop or tablet) they use to access the service.

3. Retired Features

In July 2014, Tata Communications introduced jamvee™ Unified Communications (jamvee™ UC, release 4.0), the next generation collaboration platform to succeed our jamvee™ On-Demand Video Conferencing (a.k.a. jamvee™ OVC, release 3.4) service.

Jamvee™ UC provides improved quality, latency and resilience, along with increased interoperability, access methods and a range of enhanced conferencing features.

As a result, we are retiring all jamvee™ OVC Desktop and Mobile Apps effective 30th June 2015. The OVC Apps will no longer be available for download or supported for access to the jamvee™ service, however the jamvee™ OVC bridging service will continue to be operational for endpoints to access the service and all existing customer PINs will remain valid.

4Fixed Issues in Release 4.5



Resolved Issue


Large distributed conferences intermittently contained video tiles with nested pictures.  This issue is resolved.


MS Lync and O365 chat legs were not removed from a conference when the 5 minute timer expired after the host deactivated the room.  This issue is resolved and chat legs are now removed like all other participant call legs.


The number of simultaneous WebRTC connections on a single call was limited, which resulted in some web client users not being able to join large conferences.  The number of simultaneous WebRTC sessions, per bridge, per call, has been increased to improve performance with a partial fix in this release.  The final fix is to come in R4.6.


Intermittently, the web bridge failed to recognize its link to the call bridge.  The result was some web users got connected to a web bridge not geographically closest to them, which could increase latency and affect the quality of their call leg.  This has been resolved, and web users are now connected to the nearest web bridge.

5Known Limitations in Release 4.5



Resolution Target


Skype Consumer video calls to jamvee™ service are not supported.



QoS access (vUTM) for Lync clients to jamvee™ service is not technically feasible.



Content sharing from C40 or C60 H.323 endpoints via VCS intermittently terminates.

TBD.  Workaround is to set endpoints in SIP mode.  Final resolution is VCS upgrade to v8.


Content sharing by host on WebRTC intermittently causes call legs to drop.

R4.5.2 – Aug. 2015


Activities tab does not retain recent transactions

R4.5.2 – Aug. 2015


Intermittently, chats on distributed calls do not reach all participants on other bridges.

R4.5.2 – Aug. 2015


iOS client is missing camera preview



Unread chats show up on back button on iOS client.

R4.6 – Oct. 2015


Video streams are intermittently distributed across more than one tile.

R4.6 – Oct. 2015


WebRTC calls disconnect intermittently with lost connection message due to limitation on number of simultaneous web connections that can be supported.  The final fix for this is expected in R4.6. 

R4.6 – Oct. 2015


Unread chat messages on iOS iPhone or iPad devices do not increment on the chat icon.


6Manual Upgrade Instructions

Special note for users of the jamvee™ app running on the Microsoft Windows Operating System who installed the application before November 1, 2014 and haven’t upgraded since:

You will need to upgrade manually to access the new features in the current client app. Please perform the following steps:

  1. Uninstall the current jamvee™ UC app:  
  1. Quit the jamvee™ UC app, if it is running
  2. Click Windows Start
  3. Click Control Panel
  4. Click Programs and Features
  5. Locate and double-click on the cid:image012.jpg@01CFF516.5E248110 or cid:image013.png@01CFF516.5E248110program that appears
  6. Follow the prompts to uninstall it


  1. PC users:
    1. Click on the link below to install the current PC client app
    2. Follow prompts to install



  1. Mac users:
    1. Click on the link below to install the current Mac client app
    2. Open the .dmg file and drag the ‘Jamvee™ UC’ icon into the Applications folder within the window that opens up.
    3. If you already have an older version of the Jamvee™ UC for Mac App installed in the Applications folder, a prompt asks whether you want to replace it with the new one that you are moving. Select Replace.  This will overwrite the previous version and if, for example, you have a shortcut in the dock this will now automatically launch the new version.

Note: If you first remove an older Jamvee™ UC for Mac App from the Applications folder and then copy the new one into it, clicking on the dock shortcut no longer works and the icon becomes a question mark because the icon still searches for the previous application version. Launching the new version from the Applications folder will result in a separate dock shortcut being created. Follow the instructions above to avoid this issue.
