Hi there, I've been using your lib behind sipsimple and blink software. All works well except one detail. If I'm receiving a incoming call, I get audio and everything but when I terminate. The other side remains active (but without sound). In the pjsip trace I get the following: #sip_auth_clien: Unable to set auth for tdta0xae9e3d8: can not find credential for mydomain.pt/Digest That's weird because everything else is working. If you could give me a pointer how I can "hack" the header from mydomain.pt to a ip address it would help debug my system! Keep up the good work!
