HDX - Configure SIP with ICE/STUN/TURN

[vfr]

Hi,

  is it possible to configure HDX systems to use ICE/STUN/TURN without having a Lync server?

Yes, this would be very interesting for us to use as well.  Any pointers to what we can provision the endpoint with would be appreciated, even using telnet API.

For what purposes?  The Microsoft implementation of ICE/STUN/TURN would be useless without first registering to a Lync environment as without a signaling path any additional features would not even be usable.

Hi Jeff,

  the purpose would be to make HDX units behind NAT work with our SIP servers with BFCP enabled. We have full control over our signalling path and could make ICE/STUN/TURN (even MS based) work with this.

We've been able to provision the endpoint with media relays using SIP provisioning (SUBSCRIBE Event: vnd-microsoft-provisioning-v2 and SERVICE application/msrtc-media-relay-auth+xml) . The problem seems to be that the HDX goes into some sort of Lync mode, where TCP/BFCP is disabled -- thus no presentation is possible.
