Abandoned Call
An Abandoned Call is an emergency Call in which the caller disconnects before the Call can be answered by the PSAP (Public Safety Answering Point).
Definition:
The capability to route a call to the particular PSAP based on the geographical location from which the call originated. Selective routing is achieved by building telephone number/emergency service number translations in the tandem central office. These translations cause the E9-1-1 database to assign the emergency service number to each telephone number based on the customer's address. Service order activity keeps the E9-1-1 database updated. The E9-1-1 database, in turn, generates recent changes to the tandem office to update the telephone number/ESN translations in the tandem database.
