VOIP At Home
September 30, 2008 General 1 CommentOne of the most common objections I hear about using a VOIP phone service to replace traditional home phones is that they work when the power is out.
This is true. They have their own power running through the lines. However, I counter with this simple argument: if the power goes out, use your cell phone to call the power company. The reality is, however, that the power company probably already knows that the power is out. But everyone has a cell phone, so why not use that?
But some people, like myself, have gone the extra mile. I obtained a UPS (not the shipping company, but a battery backup) for my core infrastructure. My UPS powers the cable modem, the VOIP box, the main Linksys router (running dd-wrt) and the main switch for all the network connections. The latter does not need to be on the UPS because if the power is out, the computers won’t work. My laptops will run on battery power and they will connect wirelessly to the Linksys router anyway.
For a long time I’ve been meaning to do a real world test to see how long the phone and Internet will stay up when the power is out. So today I unplugged the power and let it run on battery.
I was surprised that after an hour everything was still working. Knowing that I needed to go shopping I decided just to plug everything back in and call it good. So I know that it will work for at least an hour.
