You can run VoIP on any ip connection, and most are now fast enough to
have it run fairly well. Have a play with gnomemeeting (which talks
to netmeeting clients - yes it's in xp, go start->run->conf).

The problem is that very few ADSL providers have true QoS over
the ADSL networks. My company has been playing with offering true
QoS over consumer ADSL (using separate ATM VCs) and so far it's
Of course, you can only guarantee quality if you control the entire
path of the data - once it leaves your network there can be no more
guarantee (without all parties in the path having SLAs).
As for calling normal phones, VoIP is just a way to get voice from
one IP address to another. You still need to gateway it to the PSTN.
