Abstract
The present disclosure relates to emergency services and more particularly, to a temporary callback system for emergency calls and methods thereof. In one illustrative embodiment, the system can include a private branch exchange (PBX) or other processing device having a pool of callback identities. When an emergency call is made, a callback identity can be temporarily assigned to the device making the call. The callback identity can provide insurance that the call is maintained. If the call between the device and answering point becomes abandoned or disconnected, the callback identity can be used to re-establish the connection. The callback identity can be released when cleared by the answering point or when a time limit expires. After being released, the callback identity can be made available to other devices that wish to make emergency calls.
