Turns out pjsip_udp_transport_start6() didn't properly register IPv6 transport type to the hash table.

I'll probably need to add IPv6 option in pjsua so that this can be tested easily in the future. cheers Benny Thanks to have read me. > > Regards, > > C?dric. > > ------------------------------ > Votre correspondant a choisi Hotmail et profite d'un stockage quasiment > illimit?.
