How do you set VLAN on a socket anyway? But assuming you can set VLAN of a socket, here's how to retrieve the SIP and media sockets in pjsua-lib. You'll need to include pjsua_internal.h. Then enumerate all pjsua_call, get the media transport of each call, and get it's socket with pjmedia_transport_get_info(). For SIP transport, use pjsip_endpt_acquire_transport() to get the UDP transport, and then just access the pjsip_transport directly to get the socket. cheers, -benny
