Skype is a joke, it's a toy for losers.
If you want quality then I can set you up a PaDSL link into out MPLS backbone as pure IP traffic. We bought our own IP switch so we are a true T1 carier and I can do your peak rate local and national calls at 0.59ppm - not bad at all.
Can do Cisco router or whatever you like but you can vary the bandwith to suit and, you get a quality of service.

Skype, what a joke. We get people asking if we can compete with Skype... we do AVAYA, it just doesn't get any better... sir..
