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.
welcome back to the Polycom Community.
All of your old posts => here <= are still open / pending as you have not marked these as "Accept as a solution".
If they are in this state nobody finding them via a community search will know if an answer or advice was useful and has helped you.
Could you therefore kindly go over them and mark or answer as appropriate ?
If they are marked as "Accept as a solution" other users can find these easier and it helps them to utilize the community more efficiently.

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.
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:

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).
Set the time interval for the phone to send STUN binding indications to keep the NAT port open and the phone reachable.
Set the time interval for the phone to send STUN binding request to the STUN server to detect whether NAT device is rebooted.
