<quoted> I have not heard of any VOIP doing 7 digit dialing. It is possible one of them spent the time and money to program it in but it's pretty rare.</quoted>
I recently had a FiOS package installed that involved porting a Vonage (VoIP) number over to Verizon. My Vonage line (in central NJ) only required a 7 digit number when calling within the same area code. Earlier with ATT Callvantage (another VoIP service), I need 10 digits, but not so with Vonage (which I believe is a pretty big outfit).
