This is the first time I've used pjsip/pjsua2 on a multihomed system but I noticed that when setting an AccountConfig's `mediaConfig.transportConfig.publicAddress` and/or `mediaConfig.transportConfig.boundAddress` to the IP address of the correct network interface (on Linux), I see errors when the call media comes in: ERROR: Unable to resolve transport bind address: gethostbyname() has returned error (PJ_ERESOLVE) [status=70018] ERROR: Unable to create RTP/RTCP socket: gethostbyname() has returned error (PJ_ERESOLVE) [status=70018] ERROR: Error creating media transport: gethostbyname() has returned error (PJ_ERESOLVE) ERROR: Error initializing media channel: gethostbyname() has returned error (PJ_ERESOLVE) [status=70018] ERROR: pjsua_call_answer2(id, param.p_opt, prm.statusCode, param.p_reason, param.p_msg_data) error: gethostbyname() has returned error (PJ_ERESOLVE) (status=70018) [../src/pjsua2/call.cpp:490] If I don't set those values, the call "works" but no RTP packets are received because it's listening on the wrong network interface (I verified this by checking the address used in the SDP sent by pjsip). Setting the TransportConfig's `publicAddress` and `boundAddress` of the Transport to the *same IP address* works just fine and is bound correctly. I verified that by looking at the pjsip debug output. I have even tried adding a hostname to /etc/hosts that points to the IP address, and once again that works for the signalling address but not the media address. Making the same call to `gethostbyname()` from say a Python script works just fine, whether I pass the same network interface IP or the "fake" hostname, so I'm not sure why pjsip is having such a problem. I'm not using ICE/STUN/TURN/etc. because it's not a NAT issue, these calls are all happening on the same local network. pjsua2 works just fine on our systems with only one network interface. It would be nice if pjsip showed the resulting `herror()` when `gethostbyname()` returns NULL. I tried adding this and other debug messages myself but for some reason I never see my printf()s in the console after recompiling and reinstalling from source. If anyone has any suggestions or ideas, I would appreciate it as I am really at a dead end here. Thanks - Brian -------------- next part -------------- An HTML attachment was scrubbed...
