For VOIP you need a USR chassis with HiPer DSP, an Edgeserver PRO(
provides the signaling for the Codec, billing and acts as the gateway). It
is still in beta until late April, early May. That is why I am not selling
phoneservice, yet! I have reduced my support cost some 1200 per month

Now Cisco has a DSP engine in the 3640, which you can plug POTS into and
carry VOIP, but then you can not scale. I use the same PRIs for incomming
voice, data, and outbound voice. The phone to phone option does not work
nearly as well as computer to phone at this time.
