To reach 911 services from your VoIP phone:
Your account includes E911 service. E911, or enhanced 911, is a location technology system that assists emergency workers in determining the caller’s location. Be aware that not all PSAPs are able to accept enhanced 911 information (E911). If this is the case for your PSAP, only some of your information will be passed along to the emergency operator. You may have to tell the operator your location or call back number.
