Hello, I successfully manage to build pjsip for S60 (3rd) and I modified ua.cpp file with my SIP details. then I installed the symbian_ua.sisx onto E65. when I run this program it seems to be correctly registering with my SIP server, however when I ring my SIP phone number from a landline... I only hear a busy tone. Does anybody have a user friendly application for S60, or can somebody provide me a link so that I can look. thanks in advance upu _________________________________________________________________ Get Hotmail on your mobile.
