Power outage is a problem for VOIP services. I got a UPS (uninterruptible power supply) at home to keep the modems, routers, and the phone alive in case of a power outage, at least for a while. I don't have any cell phone service, but I got a spare cell phone sitting on my desk which apparently allows emergency calls only. So, I am hoping I am covered for 911 calls. Received my modem and ATA today. All I can do at this point is hope for the best.
EDIT: Sorry about the number of "I"s.
