If you are happy with CenturyLink, I would stay put. I only contacted Vonage customer service once and was not totally impressed even though they fixed the problem. They said I changed a setting but I didn't agree.

I've had it up here in North Carolina with my AT&T DSL VOIP phone line and it worked great. I switched to Time Warner for internet and VOIP phone (long story) and NoMoRoBo absolutely does nothing now. Apparently they work well with some ISPs and not so well with others.

I just want everyone to know that I posted this about nomorobo as many people always complained about getting unwanted calls. I am not a rep but it worked for me.

I receive no benefit from this service so if it works for you, great!!! If not, you right back to "business as usual".
