Abstract
The invention is directed to methods (and corresponding apparatus) for accurate transmission of an ELIN/callback number from an emergency caller after the emergency call goes on-hook. The methods include (upon initiation of an emergency call) the steps of storing an emergency location identification number and/or callback number in a buffer; and, upon detecting an on-hook event, transmitting the ELIN and/or callback number from the buffer. According to a preferred embodiment of the invention, the emergency call is disconnected after said step of transmitting; and prior to said step of transmitting, optionally first over private network and to the public network PSAP, a timer is initiated. The step of disconnecting is performed after the timer expires.
