Questions about switching to VOIP

[M A V I C]

I'm officially tired of Qwest. I pay for their Call Rejection service, but it doesn't work for toll free numbers. They tell me I can use their Call Trace feature at a charge of $1 per use, and after three successful traces they will start an investigation into the callers. That may lead to them being able to block individual numbers. In an email conversation, I said I'm already paying $70+/mo for my phone lines, and it's an insult to ask me to pay more for call rejection when I'm already paying for it. (There's only one # that makes calls like this, and I googled the number and it seems to be a telemarketing company that has a messed up system which just leaves blank messages or doesn't say anything when answered.)

Today I got another call from an 888# and I googled it. It was Network Solutions. Apparently since I registered a domain name with them ten years ago, they have an "existing business relationship" so they can call me even though I'm on the Do Not Call list. I read others experiences with calls from that number, and it appears to be some outsource company that has really bad customer service.

Right now I basically let them call five times without leaving an intelligible message and then I block the number. Well, that's what I want to do. Qwest wont block toll-free numbers, and has no plans to.

I currently have Comcast cable internet. I do not subscribe to their TV service, though I was thinking of getting the basic cable for $8/mo since they started charging me $10/mo extra for not having TV. They offer a digital phone service in this area. What are the advantages of it over the other providers?

Also, what are all of the other providers? Sun Rocket, Vonage... and what else? Where can I learn more about the pros and cons of each?

Thanks.
