Hi All,
Im trying to make Opensips + RTP Proxy works .
My Configuration works well , im sucesfully rewriting private IP ,
sucesfully have 2-way audio
But when i call from NOT NATED client to NATED client , and initiate
BYE request from NO NATED client request is getting private IP
85.13.245.142 is server
85.13.245.139 is not nated client
On this , i get hang up call on nated client , but client who is
behind nat did not get BYE command and dont hang up the call .
Im also attaching .cfg which is full of stupid and unneccessary
command which i have added as im desperate with this issue.
Also noticing that i have rtpproxy_offer/answer on bye command because
i was thinking that it helps but not.
Thanks
Here is debug log from opensips
