Hi Benny/Nanang I am trying to use pjproject1.0.1(symbian_ua_gui using APS). when i am trying to call from my E51 device or when i am answering any incoming call then it is rebooting.. before rebooting on my application screen it shows "InputStreamInitialized 0" then i have tried this (changing frame size) http://trac.pjsip.org/repos/wiki/FAQ#symapsprob but same result. I have also tried using "ticket #680<http://trac.pjsip.org/repos/ticket/680>.". but i got same result.... can you please have a look on this.. My device is Nokia E51. Thanks -- S. M.
