Description (partial)

This is an enhancement request to support TURN as the media relay server for Cisco Jabber.

From Cisco Jabber 12.5,  we support Interactive Connectivity Establishment (ICE) passthrough to allow MRA-registered Cisco Jabbers to pass media directly between endpoints using Host or Server-reflexive candidates. Currently, as per design, Jabber does not support TURN (Relay address) for media path negotiation. 

Which means that, if host/server reflexive candidates failed for ICE negotiation, we will keep use the JabberA > VCS/E > VCS/C > VCS/E > JabberB as the media path.

The normal process for this should be:
1. Both two Jabber are over MRA
2. Call setup and media connected successfully, its JabberA > VCS/E > VCS/C > VCS/E > JabberB
3. After media connected, both Jabber A and Jabber B will try to do ICE negotiation.
4. If host/server reflexive/peer reflexive could negotiate successfully. Switch the media path to Jabber A <> Jabber B.
5. If it failed, and only TRUN relay can be used. Keep the media path JabberA > VCS/E > VCS/C > VCS/E > JabberB

Cisco Jabber 12.5 registered over MRA with TURN configuration
