Sounds great :)
Hope you'll find sipXtapi useful and help us with sound quality improvements.
Really, sipXtapi is the only cross-platform VoIP library with full
integrated stack --
from audio play/capture to high-level call management. Problems with sipXtapi
lies in the fact that it was used with GIPS VoiceEngine for a long time and
sipXmedaLib is not very mature now.

sipXtapi's underlying libraries really lack good documentation. So we're open
to documentation-improving patches. ;)
