[SR-Users] WebRTC - XOR-MAPPED-ADDRESS and bridge mode

just an update to this issue, this was caused by rtpproxy not answering to
a stun binding request but rather relaying it downstream. (for which
asterisk as pstn terminator replied with a binding success)
i wonder how difficult it is to add stun into rtpproxy? mediaproxy-ng
should work but it does not support bridge mode. any other options?
time to move this discussion to the other mailing list :)
