Hi All and Benny; I have a problem with mobile pjsip setup.. I can able to register the client but it seems like transportation is stopping :S udp_on_read_complete calls register call backs fine.. But when i try to call a number .. It never pass from udp_on_read_complete .. after a while on call state call back called with Disconnected msg from timer.. as you can see from below.. I defined Windows Mobile at config_site.h.. Do you have any idea why calling is not working in a weird way .. sip.exe!on_call_state(int call_id = 0, pjsip_event* e = 0x2841e0e4) Line: 1046, Byte Offsets: 0x88 C++ sip.exe!pjsua_call_on_state_changed(pjsip_inv_session* inv = 0x005499c0, pjsip_event* e = 0x2841e0e4) Line: 3080, Byte Offsets: 0x648 C sip.exe!inv_set_state(pjsip_inv_session* inv = 0x005499c0, pjsip_inv_state state = 6, pjsip_event* e = 0x2841e0e4) Line: 227, Byte Offsets: 0x110 C sip.exe!inv_on_state_calling(pjsip_inv_session* inv = 0x005499c0, pjsip_event* e = 0x2841e0e4) Line: 3259, Byte Offsets: 0x2a4 C sip.exe!mod_inv_on_tsx_state(pjsip_transaction* tsx = 0x0054ad54, pjsip_event* e = 0x2841e0e4) Line: 565, Byte Offsets: 0x88 C sip.exe!pjsip_dlg_on_tsx_state(pjsip_dialog* dlg = 0x00547944, pjsip_transaction* tsx = 0x0054ad54, pjsip_event* e = 0x2841e0e4) Line: 1908, Byte Offsets: 0xf0 C++ sip.exe!mod_ua_on_tsx_state(pjsip_transaction* tsx = 0x0054ad54, pjsip_event* e = 0x2841e0e4) Line: 180, Byte Offsets: 0x54 C sip.exe!tsx_set_state(pjsip_transaction* tsx = 0x0054ad54, pjsip_tsx_state_e state = 6, pjsip_event_id_e event_src_type = 1, void* event_src = 0x0054ae58) Line: 1116, Byte Offsets: 0x1fc C > sip.exe!tsx_on_state_calling(pjsip_transaction* tsx = 0x0054ad54, pjsip_event* event = 0x2841e160) Line: 2166, Byte Offsets: 0x128 C sip.exe!tsx_timer_callback(pj_timer_heap_t* theap = 0x00430230, pj_timer_entry* entry = 0x0054ae58) Line: 1057, Byte Offsets: 0xb4 C sip.exe!pj_timer_heap_poll(pj_timer_heap_t* ht = 0x00430230, pj_time_val* next_delay = 0x2841e1c8) Line: 519, Byte Offsets: 0x17c C -------------- next part -------------- An HTML attachment was scrubbed...
