Hello, I install PJSIP(rev.2259) in my E65. I got an problem to using this. That is when I start this application then this register with my Asterisk server successfully. But when I want to change my IP, User and Password and press on done then it failed and give an assertion fail message. I got this assertion in 591(pj_assert(uri != NULL);) line in pjsua_acc.cpp file. I test this in emulator that is ok. Please give me an solution how can I resolve this. Thanks, Salahuddin Ahmed
