I jump on board with VOIP.
I decided to go with Vonage. It helped that a relative of mine uses the service and I got two months free being a new customer from a referral.
Advantages from Optimum Voice or AT&T CallVantage:
1. I keep my existing phone number (OV cant do this)
2. No contract (OV and ATTCV have contracts)
3. Cheaper plans - I signed up for $14.95 a month with 500 anytime minutes and all the features Vonage offers. (OV - $34.95 per month, ATTCV has $19.95 per month - local calling only or $24.95 per month unlimited. I can change anytime to the Vonage unlimited plan anytime.
I signed up last Friday (Black Friday), received my telephone router yesterday, service is online (with a virtual phone # till house # is porter over from Telephone company). Simple to set up too and my wireless router works with this telephone router too.
I've eliminated the nagging AM Radio signal in my phone that I have had for 5+ years on my house line that AT&T and Verizon could not fix.
