When you’re using your Internet connection for access to digital cable or VOIP there can be issues with connectivity if your Internet connection fails. Your computer needs to be connected to the Internet through a broadband or DSL connection in order for your VoIP phone to work. Although the computer does not need to be turned on, the connection must be maintained.
The connection for VoIP is maintained through the cable connection, which typically requires a modem to function. This modem needs to be powered on to maintain a connection. The actual digital portion of the connection remains available even during a power outage. Internet connections are very reliable and experience few outages. The outages are kept to a minimum because there is usually redundancy in the equipment that supplies your connection.
If you are concerned about power outages you can purchase a UPS (uninterruptible power supply) system that you can plug your computer into. Be sure to purchase one that is rated for the amount of amps you want to draw – basically, remember that you will want to plug your telephone into the UPS as well as the computer, modem, speakers and any other peripherals. The more things you plug into your UPS system, the more power you will draw and the less time your system will be kept up.
Some VoIP users keep a cell phone for emergency communications. You may also opt to maintain basic phone service on your regular telephone line for emergency use.
