Hello,

 

Thanks for your reply. The MAC address of one of the phones is 00:04:F2:DE:65:C7. Your help is greatly appreciated. 

 

Thanks,

Strictly speaking this may not be a Polycom VVX issue.

 

This is a common issue with ITSP and Lync / SfB. (http://www.ucguys.com/2013/11/lync-calls-drop-after-30-seconds-using-itsp-sip-trunking-providers.htm... What type of trunking are you using?

 

Enabling session timers would confirm if this is the issue and resolve it quickly with little potential for adverse effects.

That is a global change for the PSTN Gateway and would rather not change that setting. The only devices that are having this issue are our Polycom VVX600's.

 

 

HP Recommended

Do you experience the issue on calls where both endpoints are internal and on the same subnet? Do you have music on hold configured?

 

What's the reson given for the failure in the QoE report?

HP Recommended

This is only happening on incoming external calls. Music on hold is enabled by default and is using the Polycom MoH. The QoE logs say Diagnostic ID 32. Call terminated on mid-call media failure where both endpoints are internal. But both endpoints are not internal. it is a external incoming call.

Hello BBRyan,

The VVX600 was sold via SCANSOURCE COMMUNICATIONS back in 16/11/2015.

 

Please be aware that is not a LYNC / Skype SKU as explained => here <= and you need to ensure you have the right amount of per device Licenses purchased from Polycom for the phones you use.

Please ensure to provide some feedback if this reply has helped you so other users can profit from your experience.

Sure, but the external endpoint isn't a Lync / SfB endpoint connected from 'outside' via an edge pool, is it? It's a PSTN caller on the other side of your mediation server / trunk / gateway.

 

The error message and behavior your describing is consistent with RTCP issue.

Hello @wagnco01,

welcome to the Polycom Community and thanks for resurrecting this old outdated post.

UC Software 5.7.2 is currently the latest supported software so please upgrade and if you still have the issue start a new post.
