The STUN in outbound is a limited subset of STUN
(Binding Request, Binding
Response, and Binding Error Response, with no attributes except
XOR-MAPPED-ADDRESS). This is described in RFC 5626 section 8. I am not
expert in STUN, but as the attributes for authentication are not used for
STUN in SIP outbound, I don't think there is a multi-domain problem.
yes, i checked that too and in outbound rfc5626, a subset of stun is
used as a keepalive mechanism only.
I did some experimentation with
http://turnserver.sourceforge.net/
recently for ICE/WebRTC testing, and this seems promissing.
thanks for the pointer. i was testing with restund from baresip
project
