I've been a vonage user for the last 3 years and have had no problems.
The only complaint I have is when will they implement call blocking.
I keep on getting calls from collection agencies for some person who use to have my number and I can't get a hold of anybody to tell them to stop calling. Call blocking would be great for this.
This sounds like a potential problem with any number, whether it's POTS, VOIP, or mobile.
Is it an option to just change your number? If I weren't planning on moving soon I'd consider changing my POTS number since I have the same problem as you do with it.
