Hi, I'm developing a Python application using the pjsua Python module. I'm behind a NAT and don't have a STUN server. I set up port forwarding for the SIP and RTP ports, and now I only need to tell pjsua my external ip address. I used TransportConfig.public_addr for this, but it appears that this only influences the SIP transport, not the media transports --- in particular not the SDP, so I don't get any incoming audio. In the command line utility pjsua, the --ip-addr option sets the public_addr for both SIP transports and RTP transports. That's nice because now the SDP offered contains the public ip address and I do get incoming audio. Do you have any suggestions? Could the pjsua module be extended to support configuring the media transports? Regards, Bram
