Battery Powered Modems For VoIP?
from the interesting... dept
A short article discussing all the known downsides to a VoIP system over a traditional landline points out that, one by one, each of these issues are being solved. The one thing that I figured was always going to be a problem was the power issue. When the power goes out, your regular landline stays on (assuming, of course, that you don’t have a cordless phone), but your cable or DSL modem shuts off, and you lose the ability to use your VoIP line. However, the article briefly mentions that companies are working on cable modems with backup battery power. They probably won’t survive through extended blackouts – but certainly could be useful for temporary power outages. Seems like such an obvious idea, I’m almost surprised it didn’t show up earlier.
