Hmm, that makes sense, I guess PBX's are very cheap and very reliable
when you think of the TCO.

But how about for Bell Canada?

Would you not agree that a large part of telcos' profit comes from
added-value features like call waiting, 3-way calling, etc. and
collect calls and other overpriced long distance services especially?

And that it is much more difficult to add more added-value features to
the telephone network than to a VoIP protocol?
