Not sure about the cost side of this, as running a SIP server that can handle a decent number of calls does have an expense. However, I use SIP for most of the calling that I do. My entire office runs off of SIP, though it still has to connect to the PSTN at some point. I would prefer to use my spare bits to transport voice all the way through to the destination if at all possible. Even the conferencing that we do sounds good when all parties are dialed into our SIP based bridge. There are just too many variables that go into voice networks to say that one technology or another is responsible for how *good* it is. --Morgan _______________________________________________ Ietf@xxxxxxxx http://www.ietf.org/mailman/listinfo/ietf
