I couldn't find reference to the "unlimited local w/500 national" minutes on the archived website that Daniel pointed me to, but the info from DevilsPGD confirms what I thought I signed up for... and the reason I changed my pcs to a 323 number so forwarded minutes would not count towards the 500 minutes.
I don't recall ever receiving notification from Vonage that the plan changed.
Vonage has been ok, I've only suffered through a few outages -- which affected everyone -- and fortunately I've never had the pain of trying to get through to them on the phone.
I've recently considered switching to Sunrocket ... the website says they can port one of my Verizon Wireless numbers (310-995 Gardena) which Vonage can not do. I guess that, along with them being five bucks a month less than Vonage for unlimited, makes SR attractive to me.
Anyone have any opinions on SR?
