HI Jose,
I was not aware its running in bridge mode, Could you post your how you
start rtpproxy?
also do you have the following in your module settings
modparam("rtpproxy", "rtpproxy_autobridge", 1)
I have a working config of bridgemode with rtpproxy will be happy to
share it with you just want to confirm your setup.
Regards
Trevor Steyn
also you dont use rtpproxy in re-invites this would cause re-invites to
skip rtpproxy im sure this is a mistake.
