I've heard a fair amount of negative technical issue with Vonage. Some local ISP companies hamper the use of this service for many reasons etc. What I like about using Vonage is that I can keep the same phone number no matter where I move to even if I move out of my county. I'm currently in a rental and could end up moving this year or 2 years from now. I don't want to have to change the biz phone number on my truck and trailer signage, biz cards etc. I prefer the use of just one number and the option of call forwarding to my cell when I'm not home. The other option was to get a separate cell phone with a recognized local prefix but . . . . all the cell providers have very spotty service here? So this is NOT an option. When ever I receive a call on my cell at home it's "can you hear me now". Any input on Vonage?
