Version 2.99 (beta 3.0, repository: 526:f5cc7178b900). Includes a .asoundrc which should work (best with headset). If you want to use your own alsa configuration put it in appdata/qutecom. Outgoing calls tested, incoming calls possibly not working (this may be a firewall issue).
27062013 update: recompiled with optimization flags
30062013 update: asoundrc corrected: on board mic now works
