California VoIP E9-1-1 Deployment Description

Voice over Internet Protocol (VoIP) is becoming an alternative to traditional phone service and the goal of the CA E9-1-1 VoIP Deployment is to get the registered location information of a VoIP user to the most appropriate public safety answering point (PSAP) via statewide standards using the 9-1-1 network.

The California 9-1-1 Emergency Communications Office (9-1-1 Office) is the primary contact to coordinate the deployment in accordance to the Federal Communications Commission (FCC) mandate 05-116A1 issued 5/20/2005.  Specifically, VoIP i2 specifies that VoIP Service Providers (VSPs) shall route their calls into the 9-1-1 network and send the registered user location information to a designated PSAP.

Most VSPs will work with a database provider known as a Voice Positioning Center (VPC) and have access to the 9-1-1 network via an Emergency Services Gateway (ESGW).  VPCs are used to store and update registered user location information and then provide the information to the PSAPs when a 9-1-1 call is made.  ESGWs are those entities, typically Competitive Local Exchange Carriers (CLECs), that provide the connection interface into the 9-1-1 network.

Our mission, together with the local exchange carriers, PSAPs, VSPs, VPCs, and ESGWs, on this deployment is to implement the best "comparable E9-1-1" service for the VoIP user that calls 9-1-1 in California and keep the network reliable and dependable.

For questions specific to the VoIP deployment, email Donna Pena at  donna.pena@state.ca.gov or contact her at (916) 657-6116.

IMPORTANT NOTE: In accordance with Governor Schwarzenegger's Executive Order, State Government Offices will be closed the first three Fridays of each month through June of 2010.  The State 9-1-1 Office will not be open for business on these days.
