In 1968, AT&T chose 911 as the easy to remember and dial number to connect to an emergency dispatch. As technology changed and services improved, Enhanced 911 was implemented to automatically identify the caller's location and will even work (when available) on cellular phones.
As Voice of Internet Protocol (VoIP) technology has taken over as the industry standard for connecting phones to the world, and if you have a VoIP phone system, you should be aware of 911 limitations.
Your service provider is required by law to register your physical location for each handset or extension. As a VoIP phone is a computer and can be connected anywhere you have internet access, it is important to inform your service provider if you relocate a phone.
Dial 933 for Location Verification
DO NOT DIAL 911 unless it is an emergency.
While dialing 911 is an option for testing, you will be in the emergency system utilizing resources and possibly accessed a charge for a non-emergency call. If you do dial 911, DO NOT HANG UP, tell the emergency personal that the call is a non-emergency and you were interested in verifying the address on file.
Dial 933 instead. 933 is an emergency verification system that will play an audio message with emergency information on file for the phone dialing into the system. Dialing 933 is a NON emergency call and will not incur any fees. We recommend that you dial 933 on each phone in your company to validate emergency information.
As an Inline Technology VoIP customer, you will be reminded quarterly to perform this test.
