OK my VOIP/SIP works on WM6 and my Internal earphone works with SIP on my TyTN WM6 (http://forum.xda-developers.com/showthread.php?p=1395705#post1395705). Thanks to the great work off that thread's contributers. I can use both the internal speaker phone and the internal earphone of my TyTN. The sound quality ,however, is another topic: mine is very choppy. I can not even judge the other quality factors.
I read a lot of SIP/VOIP postings but did not find much on improving the audio quality under WM6. Third party SIP clients most times have codec, jitter, buffer and other voice and audio adjustment possibilities. The only very technical reference I found is Windows CE Networking Team WebLog (http://blogs.msdn.com/cenet/archive/2006/12/08/rtc-1-5-useful-registry-keys.aspx).
I can compare the audio quality of my HTC TyTN WM6 SIP with a Linksys WIP 330 WiFi phone (WM 4.2, SIP) through the same WiFi Router. ADSL at above 10 mbs and 1 mbs upload. The WIP330 sounds is a bit sharp (high hiss), but almost no chopped off sound.
Perhaps the lack of those features is why HTC left SIP support out under WM6?How is your audio quality on your device under WM6?
