When you move to an internet based phone system, you are reliant on the connectivity of the internet to maintain phone connections. If you lose power to your building for any reason, you will also of course lose your modem/router and thus your internet connection.
Implementing a UPS or Battery Back Up is designed to maintain the power to the important elements of the phone system such as the modem, switches and IP phones to at least allow you to complete calls that are in progress and shut down hardware safely. You can speak with the Sky Booth team if you would like to extend this back up to longer periods of time but we focus on a back up of 20 to 30 minutes to ensure a high level of customer service to your clients in the event of a power failure at your premises.
