Vonage sucks.  Don't use them.  If you do, I'm really sorry.
I've had Vonage for little over a year now.  Things were good up until a few months ago, and then the voice over IP router thing they sold me started having issues.  I used their online knowledgebase to see what they had and nothing helped.  I took packet captures (yeah, I'm a geek, but that's my profession) and there were definately some problems going on with the hardware.
So instead of calling their technical support line, I just call my local CLEC (phone company) and setup a second phone line.
I called Vonage after the fact and they were going to charge me $70 to disconnect.  That $70 is to recoup the $70 rebate they gave me on their phone router thing since I was canceling before 1 year.  They said if I waited a month, I wouldn't have to pay $70.  They also gave me a month's worth of free service, which I didn't use.
So I waited.  And the month went by.  And I didn't cancel.  So they charged me for another month's worth of service.  So I called.  Want to cancel.  No refund of monthly charge, which is $30.  And they want to charge me $40 to cancel my service (that was a part of your terms of service - if you cancel less than two years after you started with us).  So I'm screwed.
Well, I'm going to dispute the charges with the credit card company.  I hope that I can do something there.  Dang stinking Vonage.  Customer no-service.  I'll be glad to get rid of them once and for all.
