[OpenSIPS-Users] Mediaproxy and ICE

[Hòa Nguyễn]

I suppose you've used engage_media_proxy() to allocate media session in
OpenSIPS
You might want to know that if mediaproxy-relay receive a little traffic
from phone then don't receive anything anymore in the next 180s, it will
assume that your phone has been crash or something and close the session,
then if you use engage_media_proxy(), the relay will send the signal to the
dispatcher to close the dialog, hence make OpenSIPS send BYE to both of
phones
I think in your situation, it can be that your phone first will send RTP to
mediaproxy-relay first, then it decides to make a P2P connection and
success, then it will uses the P2P and don't send anything to relay
anymore, that make relay release the session and close your call. The
solution is not using engage_media_proxy, instead using
use_media_proxy/end_media_session
