Hello again PJSIP people, forgive me if this has already been properly discussed or documented elsewhere, but I have searched and not found the answer. My app is running on a linux box with multiple interfaces. I'm not using PJSUA, rather just the base PJSIP/MEDIA/etc functions. What happens is during a SIP dialog, the SDP address and Via: fields are always automatically populated with the IP of the first interface. However, I am binding to another interface in *pjsip_udp_transport_start*. Ultimately I will be bridging calls across multiple interfaces, and I need a way of directly controlling the IP in the SDP and Via fields for each invite dialog. Could you point me to documentation or a quick example which explains how to do this? Thanks in advance. Mark -------------- next part -------------- An HTML attachment was scrubbed...
