Great software!

Using with CallCentric, works great! Purchased G729 codec - outstanding quality and low latency! I used iSip for quite some time but I recommend media5 if you use VoIP a lot (better quality calls especially with G729.)

Please implement a ringer volume control, and also a volume control for the DTMF dial pad. Tones and rings are far too loud.
