I too have reason to believe that the cable/network equipment out there has battery backup. Both at my house, and at my Dad's house, the vonage phone (and internet) continue to work despite moderate power outages. I don't think it would stay on for days on end though.
That being said, certain types of events are still liable to take the systems down. Remember that fire (they thought was a bomb at first) at One Broadway in Kendall Sq, about 8 months ago? I support offices in that building and across the street, who use SIP trunking commercial services. When the emergency crews arrived to the scene, they shut down all the electronics everywhere, cut power to the grid, and everything stopped. So a battery backup in the offices there didn't save me from anything. For home I use vonage, and cell phone backup. For offices I use SIP trunking, and one copper line for 911 backup. -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Kevin L.

I would have thought the same, but I've had neighborhood power outages that did not affect my network connections on my UPS-protected machine at all--perhaps the amplifier boxes in my area have battery backups? -- Kevin L.
