Don't be so harsh about VoIP as its simplicity is generating a whole range
of useful applications.  There is a war going on out there to hold off
VoIP.  VoIP is having problems with the old phone companies and cable
providers who are blocking where possible or reducing its effectiveness.  An
former FCC lobbyist is the FCC chair, many rulings have hurt VoIP
deployments.   The last century telephone companies use their long standing
monopoly positions to keep VoIP out.  That accounts in some part for well
known VoIP sound pauses.  I've found the VoIP sound quality way above the
POTS network.   Search the issue "net neutrality" for some insight.

As an example, a VoIP phone system put the U.S. Bond Trading market back in
operation within a few days after the 9-11 attacks.  The POTS network could
not do that in that time frame.  When I call a friend in California who has
a VoIP service I can hear street traffic in the background.  When calling
this same person on a POTS line I don't hear that traffic.  Based on the
flexibility, programmability, and the accessibility of SIP we will see some
new ways of thinking about communications in a way the old telephone
companies will not do voluntarily.
