Thanks to the intensive help I got in this mailing list I finally got my copy of pjsua_wince up and running on a mobile device (WM5). The problem I am experiencing is as follows: Whatever I speak in the mobile device is heard by the other side (a soft-phone on the desktop). However, whatever I speak to the microphone on the Desktop it is not heard on the mobile device. I followed the checklist on the wiki when applied and it seems like the device is working properly in other cases (playing wav, etc.) -------------- next part -------------- An HTML attachment was scrubbed...
