911 Requirements on Voice Circuit

Since a voice circuit can have dozens to hundreds of numbers (DID’s) associated with it, it is important to list the main business number for identification and location purposes. A call to 911 from a business that has a voice circuit with many numbers can lose time in getting help to the correct location unless the information is recorded correctly by the service provider. The 911 system tries to automatically associate a location with the origin of the call. See also E911.
