Abstract

An approach is provided for receiving a voice-based emergency call and routing it to a local Public Safety Answering Point (PSAP) along with anchoring information identifying the caller and their location. The PSAP may provide options for the caller to choose to use non-voice-based messaging service concurrent with the voice-based emergency call. If the caller desires and chooses to communicate via non-voice-based messages, then a text messaging application at the PSAP is used to communicate with the caller. The PSAP utilizes the anchoring information obtained from the concurrent voice-based emergency call when communicating with the caller.
