Hi! I have build a Windows Mobile dialer using MFC smart device application with PJSIP with Windows Mobile 6 Professional SDK and configuration. When I am deploying and debugging it on Windows Mobile 6 Professional Emulator. Then every thing goes fine until I press REGISTER Button to send the registration uri to SIP Server it also gets suceed as seen in Console debugger of Emulator as mentioned below: pjsua_acc.c Registration Sent But No response from the server is coming back so after some seconcds the emulator gived the below response. pjsua_acc.c SIP registration failed status=408 <request timeout> Also I have traced the network packets on the PC on which Emulator is running but no SIP packets were exchanged and also I checked that no packets were received on the SIP Server which means that the Emulator is not transmitting the Packets to network properly. It may be due to any configuration issue in Emulator Internet Settings or Some settings to be done in PJSIP. I have browsed a lot on internet for this but no help yet. Please help me out in this. Is there any proper way to connect Internet in emulator for these type of applications. -------------- next part -------------- An HTML attachment was scrubbed...
