hi, I am new in windows mobile and I am trying to make a simple call using pjsip in windows mobile emulator, I make a dll of pjsip using sipek project and used in my project, it loaded successfully, and when I try to register it gives a request timeout error, and it returns a status value of 408, I am confusing weather the unsucessful of registration is due to my configurations of the emulator or do I have to change any code in the pjsip, Here is my output of the console of the emulator: ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------ CertVerify: \Windows\CoreCon1.1\CMAccept.exe trust = 2 RaiseException: Thread=9728c9f0 Proc=80096a90 'EmulatorStub.exe' AKY=00000201 PC=00018340(EmulatorStub.exe+0x00008340) RA=88037538(NK.EXE+0x00007 538) BVA=00000000 FSR=00000000 CertVerify: \Program Files\mobile\mobile.exe trust = 2 CertVerify: pjsipDll_mobile.dll trust = 2 13:00:22.000 os_core_win32. pjlib 1.0 for win32 initialized 13:00:23.000 sip_endpoint.c Creating endpoint instance... 13:00:23.000 pjlib select() I/O Queue created (0015DB64) 13:00:23.000 sip_endpoint.c Module "mod-msg-print" registered 13:00:23.000 sip_transport.
