[OpenSIPS-Users] Opensips altering RTP port in SDP??

[Bogdan-Andrei Iancu]

Hi Nauman,

OpenSIPS by itself does not change the SDP content, only if instructed 
by the config file, by using function from nathelper/mediaproxy 
modules.  Do you use any of them ?

Regards,
Bogdan

It seems to be because the Bria client has an RTP port of 4000 which gets remapped to something higher eg 4100. This then results in one way audio. Are there any reasons that Opensips would alter the  SDP m=audio line. We are using a Netgear router but don't believe this is modifying anything.
