[Tfug] VOIP

[johngalt1]

As an alternative to land line hell how practical is cheap
or free VOIP over DSL or cable?  What is the downside?

What do TFUGgers use for this application if anything?

Is DSL pricing dependent on having a landline?

What kind of card do you need to use with an Asterisk server
to plug in your POTS equipment?

What about unlocking a Linksys PAP2 instead of using
Asterisk?

I need to use dial-up to access stuff at work.

Questions, questions. TIA
