If my power goes, does my 911 service still work?

Blue Stream Digital Phone service provides up to 4 hours of battery backup. So long as your battery backup is not uncharged, discharged, improperly installed or malfunctioning, your phone service will continue to work even if you lose electrical power. This includes your E911 service. Note that it’s important to have a battery backup telephone to use at all times in case of power failure.
