I have had Sunrocket for 3 months and it's been great! I save a bunch of money every month and have had no problems with voice quality etc. I have had no outages and the Customer service has been excellent as well.
The referral program and the signature number are 2 additional things that set this service apart from Vonage and some of the other residential VoIP vendors.
The FREE phones received when starting up are also great phones that work well with great range and features.
Use this code for signing up 3035520408 and you will also recive the phones!!
