Abstract

An i3 proxy module is provided within a 911 service provider network (e.g., at the VoIP positioning center) to respond to a VoIP i2 SIP INVITE destined for a PSAP having i3 architecture. The i3 proxy module responds to the VoIP i2 SIP INVITE by generating a VoIP i3 SIP INVITE with PIDF-LO and routing the same to the i3 emergency services routing proxy (ESRP) within the i3 network. Thus, an i3 SIP INVITE with PIDF-LO is sent from an i3 proxy module associated with an i2-based VoIP positioning center (VPC). Thus, legacy originating service provider (OSP) carrier networks are now enabled to route an emergency call to a PSAP having an i3 ESInet architecture.
