Hello,

Does somebody know whether pjsua_wince can work on a Windows Mobile device
connected to the internet through ActiveSync.
When I tried to make registration to the server, it failed.
I opened Wireshark on my computer to see the traffic, and I could see that a
SIP registration message was sent to the server through the computer, the
server responded,
but then the SIP traffic stopped. Maybe the computer doesn't transfer
messages back to the mobile device for some reason?

I'll be glad if someone can help me. Maybe there are some settings on the
mobile/computer that I need to change.

Thanks,
Emil.

As stated, for the emulator you need to setup virtual network drivers (Virtual PC 2007). Check the video on the URL I sent, it works for me.

For mobile device itself, I'm not sure what the problem is. TCP should work with ActiveSync "out of the box". Maybe you have some option disabled in AS itself. Test it with web browser on the mobile device - if it works, TCP is OK (UDP won't work in either case).

Check the networking (assigned IPs & such) on the device. You can use this tool: http://www.cam.com/vxutil_pers.html.

Thanks for helping, but now I'm a little bit confused.
Did someone succeeded connecting from the device to the SIP server (through the ActiveSync connection)?

I tried to do it from the emulator and it didn't work even though I could access regular websites.
I've also succeeded accessing websites when the device is connected to the computer through device manager center (I have Vista), but I couldn't connect to the SIP server.

Also TCP doesn't work. Not only UDP. From looking at wireshark, it seems that packets that come from the server to the PC, are not transferred to the device. I think that this the point where I should concentrate.

I'll be glad for more advices.

Thank you,
Emil.

Hi Emil.

Had a similar problem. As far as I know ActiveSync does not support UDP packets, so it was impossible to debug directly on the device. So I used wifi connection. The next problem was that pjsip defaulted with the ActiveSync IP, so I added the 169.*.*:* filter in the code. Now it works just fine.
If you use emulator then you have to setup the virtual networking. Instructions are here: http://msdn.microsoft.com/en-us/netframework/cc952340.aspx
