STUN Support


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

Hello KL,

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. 


Best Regards
