I have had Vonage service for almost two years. I an using Vonage over a Verizon DSL 728/256 down/up connection. Vonage has work fine when all I want to do is call one person (so long as I am not uploading some large files at the same time).
Unfortunately, I have never been able to 2 way (never mind 3 way calling). The voices are choppy to the point of incoherence.
Has anyone been able to us Vonage successfully for more than just one way calling? What up/down bandwidth do you have?
