Dear all, I use PJSUA on Symbian (v9.1, S60 3rd Ed. - initial release) to handle VoIP calls on Nokia E65 handset. When WiFi is on, I initialize PJSUA to register to Asterisk, it's OK. But when WiFi becomes off, I destroy PJSIP by using pjsua_destroy(), then re-initialize PJSUA when WiFi turns on again, and at that time, PJSUA crashes down (this causes my application crashs, too). I don't know the reason why PJSUA gets error when destroy and re-initialize on Symbian. Anyone knows about this problem? How to fix it?
