I would Cancel any VOIP Since you still need a high speed connection its not worth it really since the local phone Co are making it now that to get VOIP it will run you about the same as a regular phone line.
I have done some research on this topic when I was trying to save some money getting a VOIP and my phone company will Charge me for having no phone service with DSL will only save maybe $5/mo
Also Phone lines are ment for voice VOIP Tech is not perfected yet and gets a lot of static, unless you have a T1 thats a dedicated VOIP
Also the VOIP runs thru your router, If you have residential DSL your router will reset itself every few hrs and will cut you off if your talking to some one. ATT is Great for doing just that. :crash:
