HI, I have successfully compiled the PJSIP Softphone application on Windows Mobile 6 Professional Emulator. The registration and calling is going fine, When I am calling to any mobile the call is going right but when call is picked up, there is no voice on either Side. Neither on PC running emulator nor on the device being called. Also I have checked the packets on wireshark all the SIP Packets are coming and also the RTP packets are coming only from server side with the GSM payload type. Also when i am calling pjsua function *pjsua_get_snd_dev* after pjsua_start() function I am receiving the deviceID as -1 in both the input device ID and receiving Device ID. When using the funciton pjsua_enum_snd_dev(pjmedia_snd_info info[], int* count) to enumerate the sound devices it returns the 5 devices in count, but in parameter pjmedia_snd_info info it gives the same name "Microsoft Sound Mapper - Input" all the 5 times. Please see what the problem is, is there some settings to connect headphones of the PC running emulator to the WM6 emulator. Thanks in advance ....Any help will be appreciated..... Regards: Ravi

As for traffic from the other direction, it is also known that the emulator puts somekind of NAT in front of it, so unless some NAT traversal methods are enabled (such as STUN) probably the packets from server won't go through.

As for device names, I haven't tested it myself on WM platforms, and I suppose there could be some potential problems due to Unicode things. cheers Benny
