E911 for VoIP Project

Background and Overview

E911 voice services are critical to providing timely responses in emergency situations. All traditional telephones on Stanford’s campus have their building’s address in the AT&T Public Safety Answering Point (PSAP) data base. When someone dials 9-911 (or 911) from a traditional telephone on campus, the PSAP knows the proper address for dispatching of emergency services.

Stanford’s VoIP sets and service provide a different set of challenges. Sets can be moved between buildings and service can be moved by logging into a different set. This creates a mis-match between the original building address information in the PSAP and the actual location of the set. Currently ITS is deploying VoIP sets with a disclaimer approved by OGC that states if a customer moves a phone, that customer must contact ITS and have the address location updated for 911 purposes. In spite of this “requirement”, we know that this does not always happen. Today ITS processes approximately 50 work requests for VOIP phone moves per month. Not having the proper address location information for the VoIP service means the PSAP could dispatch emergency services to the wrong address.

The RedSky E911 Manager allows automated management of location data for all VoIP telephones by establishing real-time location discovery of IP phones on the network. This product is tightly integrated with the CS2100 product to automatically track, manage and deliver life-saving location identification information for re-located VoIP sets on the Stanford campus.

Risks of Not Doing Project

  1. Incorrect location/address information in PSAP could result in delayed emergency services because they are sent to the wrong address.
  2. The University could have significant liability issues.

Project Team

Role Primary Responsibilities
Project Sponsor Bert Stubbs
Project Manager TBD
Product Manager Christine Moe
Business Owner Bert Stubbs
Operations Owner Christine Moe
Client N/A — Infrastructure Project


  1. Provide real-time address/location information for 911 calls from ITS supported VoIP wired sets.
  2. Allow additional VoIP set mobility on campus. This could eliminate the need for a client to cut a work order to move their voice service from one VoIP enabled building to another.


Output Description
Procurement Procure equipment and associated peripherals.
Installation of RedSky system and integration with CS2100
Test on the University VoIP network Configure all equipment and test functionality and integration with campus VoIP Network.
Test on the Hospital network. Configure all equipment and test functionality and integration with Hospital Network.

Project Scope

  1. Implement E911 relocation for all ITS provided VoIP wired sets.
  2. Integrate with Pinnacle system so new location information is updated in records when a set is moved.
  3. Review Phone Move process to determine impact of E911 automation.

Issues, Risks, and Mitigating Factors

Issue/Risk Likeli-hood (HML) Impact (HML) Mitigation
Network architecture or security will not allow discovery of sets. L H None — gating factor.
