Hi All I have successfully registered to the server using pjsip but when I try to make call, I got 407 proxy authentication and pjsip send ack but not send register packet again after ack packet as it should send register packet with diegest information. When I tried using Xlite and other softphone, they sends register packet with diegest information after 407 proxy authentication message. Any body have some idea, how to resolve this error.
