STUN Support

Does the Polycom VVX line support STUN for use with Open SIP platforms? We would like to use the 3CX phone system, but 3CX claims they can not remotely provision a Polycom VVX phone because Polycom does not support STUN.

 

Searching on Google, I did find a mention of 66597 Added support for Microsoft STUN/TURN/ICE.  in Polycom UC software 4.1.0 Revision S is for use with Microsoft® Lync® Server and using a single registered line only. This mentions for Microsoft enviorments, but what about for open SIP platforms?

 

Does Polycom supports STUN, and if not then why not? It seems Yealink and other large SIP Phone manafactures do.

Re: STUN Support

Forgive me if I somehow missed it, but I'm not seeing an answer to the question. I understand KL should accept answers to past questions, but this question needs an answer.

 

General STUN support should be a given for any SIP device, but I'm not seeing mention of it outside of Lync.

Re: STUN Support

Hello @RyanBair,

welcome to the Polycom Community.

The original poster has asked many questions prior without ever showing any reaction to the answers.

 

As this does not help the community to grow I decided to remind him of this prior to answering his new question.

 

To answer this finally at present we only support STUN for Skype for Business and not openSIP.

 

If you require this I suggest to work with Polycom sales to raise a feature request for this:

 

Jan 03, 2013 Question: How can I request a change to the current Polycom SIP / UC Software?

Resolution: Please check => here <=


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

Re: STUN Support

Hello all,

 

just to follow this up STUN is supported since UC Software 5.9.5 for Legacy VVX and 6.1.0 for the rest of the VVX range.

 

Session Traversal Utilities for NAT (STUN) Parameters


Poly UC Software 5.9.5 supports Session Traversal Utilities for NAT (STUN), a network protocol used in NAT traversal for real-time IP communications, such as voice, video, and messaging. This section lists parameters that configure Simple Traversal of UDP though NAT (STUN).

 

nat.refresh.interval

 

Set the time interval for the phone to send STUN binding indications to keep the NAT port open and the phone reachable. 

  • 30 seconds (default) - The phone sends STUN binding indications for every 30 seconds to keep the NAT port open and the phone reachable.
  • 0 second - Disable STUN Binding indication to refresh NAT bindings.
    3600 seconds

nat.device.pollInterval

 

Set the time interval for the phone to send STUN binding request to the STUN server to detect whether NAT device is rebooted.

  • 60 seconds (default) - The phone sends the STUN binding requests to the STUN server for every 60 seconds. If NAT IP address or the port details in the STUN binding response don’t match with the previous binding response, the phone automatically restarts.
  • 0 - The phone doesn’t check whether NAT device is rebooted. If NAT device is rebooted and the NAT IP address or the port is changed, the phone doesn’t receive any incoming messages as the IP address and port details published in SIP register message don’t match. You need to restart the phone manually to make the changes effective. Poly recommends not to set the value as 0 seconds.
    900 seconds
