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 ?

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.
