You need to implement a registrar. Unfortunately there's no ready to use registrar sample in pjsip samples, so you'll have to do it the hard way (read RFC 3261, read pjsip docs, and figure out how to implement it with pjsip. ;) ). cheers, -benny > Thank you for your help! > > Best regards, > Helmut > > > -----Urspr?ngliche Nachricht----- > Von: pjsip-bounces at lists.pjsip.org [mailto:pjsip-bounces at lists.pjsip.org] Im Auftrag von Benny Prijono > Gesendet: Donnerstag, 18.
