I'm new at learning all of this stuff as it relates to VoIP, etc. So,
the "ATT CallVantage" service can be utilized over a DSL or Cable
connection, right? I guess what seemed confusing to me is if it can
be used over a DSL connection, then in order to have a DSL connection,
you usually have to have a regular landline, correct? Well, what
seemed odd to me is why anyone would pay for a landline in order to
have DSL service just so they could have the "ATT CallVantage"
service, unless a person could subscribe only to DSL service without
landline service.

[TELECOM Digest Editor's Note: There are at least two forms of
'broadband' internet (or considered 'fast enough' for applications
such as VOIP service). There is DSL, which is a telco service, and
there is 'cable internet'. Cable is quite independent of your phone
service. They are a lot the same, but many of us feel that cable is
generally a bit faster. I used to have DSL when I was a customer of
Southwestern Bell Telco; I have been with Cable One now for a few
years, for both television and internet. I do not know if AT&T will
sell their 'CallVantage' service to people who do not have DSL
service. A few of us can easily have both DSL and cable internet,
but there are many people eligible for one (because of their location)
but not the other. Many of the cable companies are now doing phone
service as well. PAT]
