Dear Alejandro, depending on how many phones you have it may be possible to have a "limp" mode operation where only essential phones (using PoE) and asterisk are kept running using a UPS. If your Asterisk box has a monitor you don't really need to power this during a power cut. Obviously, the larger the UPS and the less it uses in a power cut the longer they will last. Usually one hour would be considered appropriate, if power outages last longer that this then you will need a generator. Your bids may not need to include a generator since if these are public government bids a generator would be considered a seperate facility item rather than a phone system specific item.
