Abstract
In a VoIP system, a method and apparatus for tracking emergency callers is provided. A VoIP service provider network includes a plurality of VoIP phones and is connected to an emergency service provider system. The emergency service provider system includes a call server connected to the VoIP service provider network; a subscriber database; a VPC SBC; and a media gateway for connection to a PSTN. The call server is adapted to receive an emergency call from a VoIP telephone in the VoIP network; verify if the SIP URI has a DID bound to the SIP URI; if the SIP URI does not have a DID bound to the SIP URI, obtain a temporary DID from a DID pool and temporarily bind the temporary DID to the SIP URI; and forward the call to an appropriate PSAP in the PSTN. Should the emergency call be dropped, a person at the PSAP can call back the emergency caller without unnecessary delays.
