PSAP – Public Safety Answering Point
The PSAP is the physical location(s) within the PSTN at which emergency services call handlers will take emergency calls from individuals in distress. Emergency services can be sent to the individual’s geographic location based on information provided verbally or through automated means based on their access network. The latest generation of PSAPs support packet based connectivity to service frameworks such as the IMS (IP Multimedia Subsystem), allowing users of an IMS to make emergency calls without having to break the call out to the PSTN.
