Line 1: An'''''ESRP (Emergency Service Routing Proxy)''''' is an [[i3]] functional element which is a [[SIP (Session Initiation Protocol)\|SIP]] proxy server that selects the ~~next~~[[Next Hop\|next-hop]] routing within the [[ESInet (Emergency Services IP Network)\|ESInet]] based on location and policy. There is an ESRP on the edge of the [[ESInet (Emergency Services IP Network)\|ESInet]]. There is usually an ESRP at the entrance to an ~~NG9-1-1~~NG9‑1‑1 PSAP. There may be one or more intermediate ESRPs between them. {{Related Terms:}} '''''Originating ESRP''''' The first routing element within the Next Generation Core Services (NGCS). It receives calls from the BCF at the edge of the ESInet. '''''Terminating ESRP''''' The last ESRP for a call in NGCS. {{RelevantNENADocs}} '''NENA-INF-011''', NENA NG9-1-1 Policy Routing Rules Operations Guide [[Category:Glossary]]
