hello
I am trying to use rtpproxy and kamailio. Below please find my kamailio.cfg file.
But this is what is happening:
1- ext 101[IP 76.109.183.2] is able to send audio to kamailio's IP [65.111.185.187]but it does not reach ext 100 IP [76.109.15.75].
2- ext 100 does not send RTP at all.
3- I still see the private IPs in the SDPs of both exts.
I am aattaching a wireshark capture
Thank you in advance
Fabian
