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.
