Voice over Internet Protocol VoIP

1
Voice over Internet Protocol (VoIP)

• Can be viewed as having a number of problems that
  prevent enhanced 9-1-1.
• Can be viewed as providing major, new enhanced
  9-1-1 features to users and PSAPs that are not
  yet even dreamed about to the E9-1-1 profession.

2
Long Term Goal

• Facilitate Migration to an all-IP environment.
• Move PSAP to IP supporting voice, essential data
  items (Callback , caller location , provider ID,
  etc), Open GIS GML, and XML data.
• Needs
• Requires network development
• Probably will require 20 digit switch upgrade
• Will often require CPE upgrades

3
Short Term Goal

• Determine how to get IP calls through the tandem
  network today.
• Provide an initial implementation option for VoIP
  E9-1-1
• Take a phased approach to full PSAP IP integration

4
Core issues

• Identifying emergency calls
• Identifying the right PSAP
• Conveying valid location information to PSAP

5
Challenges

• NENA Future Path Plan requires no existing
  features and/or functions are lost with new
  technology.
• The highest priority is to restore the E9-1-1
  features to VoIP end users today.

6
Challenges(continued)
Evolve E9-1-1 to take advantage of new technology
while providing essential data items to the
PSAP. Look for future possible features, such as
video, non-voice data, where all data can be
available to 9-1-1 services
