Polycom VVX Phones Not Ringing for Incoming Calls from CUCM via SIP Trunk to Skype for Business

Here is the specific call flow that I am having an issue with:

 

Cisco CUCM -> SIP Trunk -> Audio Codes Gateway -> SIP Trunk - > Skype for Business Pool

 

Calls to and from Cisco CUCM to the Skype for Business environment work without issue on both the Polycom phone and Skype for Business Windows client without issue with one exception; the Polycom VVX 501 (or 601) will not ring or be able to answer the incoming call from CUCM. It can place an outbound call to CUCM without any issue. It can receive Skype calls without issue.

 

I have done quite a bit of searching for an answer on this and I actually found a thread from 2013 of someone dealing with a very similar issue:

 

http://community.polycom.com/t5/VoIP/VVX-410-310s-do-not-ring-when-called-from-Legacy-PBX/td-p/43399

 

I have collected some output from both the Audiocodes gateway as well as Skype for Business that seems to be relevant (output sanitized):

 

From Audio Codes Gateway:

Re: Polycom VVX Phones Not Ringing for Incoming Calls from CUCM via SIP Trunk to Skype for Business

Hello tjackson,

welcome to the Polycom Community.

It is always useful to include the currently used UC Software version as issues experienced may already be addressed in a newer release.

This also allows yourself and others to check against current software release notes.

The above is also stated in the "Read First"

Therefore the Polycom VoIP FAQ contains this post here:

Question: How can I find out my SIP UC Software Version or the BootROM Version of my Phone?
Resolution: Please check here

The log snippet you posted does not show any Polycom phones.

 

In order to try and help to troubleshoot we would need to see more logs. Please open a Polycom support ticket.


In order to raise a support ticket you need to work with your Polycom reseller as they need to do this for you. In case this is some sort of an Internet discounter please post your phone's MAC address so I can look up who would be able to support you.

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

Best Regards

Hello tjackson,

SCANSOURCE COMMUNICATIONS is your Tier 1 support contact and the phone should be running 5.4.4 as the latest supported release.

I just upgraded the phone to 5.5.0.20556 since that was available and it has seemingly made no difference.

Hello tjackson,

The community's VoIP FAQ contains this post here:

Jun 15, 2016 Question:Can I use UC Software 5.5.0 for Lync or Skype for Business deployments?

Resolution:UC Software 5.5.0 has not been qualified by Microsoft to use in Lync or Skype for Business deployments. Polycom will not support UC Software 5.5.0 use in Lync or Skype for Business deployments.

 

I did state to upgrade 5.4.4 and further work with your Polycom reseller.

I have downgraded the firmware to version 5.4.4.3041 and the problem still persists. I will try to reach out to tech support but if anyone else has any suggestions on this it would be greatly appreciated.
