What is voice over IP

The future of Voice over IP

How Voice over IP will affect 911 calls

How Voice over IP can be used to assist the 911 Dispatch Centers

• Originates in IP over a Broadband Connection

• Unique CPE (adapter or IP phone) • This CPE is essentially the same as “cordless phone” technology in that if power goes out, so

does phone; phone can be physically moved at the whim/will of the customer

• Nomadic • Anywhere you can get a high speed Internet connection.

• Provides integrated capabilities and features that allows the end user to manage personal communications dynamically.

• Rich features and functionality• Follow me• Distinctive ring• Voice mail over the internet• Selective call answer/selective call forward

Voice over Internet Protocol. A technology for transmitting ordinary telephone calls over the Internet using packet-linked routes. Also called

IP telephony


At its core, VoIP service is the 100-year voice product delivered over a new technology that enables lower price points and advanced features.

Timeline

Residential VoIP Martket Growth

Over 30 Million subscribers in the U.S. will use VoIP by the end of the decade.

• Voice will be the smallest piece of the pie

• Bandwidth to provide music, video and always on services

• Micro-mobile solutions as phones and PDAs

• WI-FI enabled cities will accelerate market adoption

• Merged

Fundamental and significant change in the communications industry is driving the need for Public Safety solutions that accommodate the many new ways that emergency services can be requested

and the response provided.

• Basic 911 A direct connection between a dial tone office and the PSAP

• Enhanced 911 Calls are routed based on location and calling party information is displayed (ALI)

• Wireless 911• Phase 0 Calls are directed to a 10 digit administrative number at the PSAP• Phase I Calls are routed based on the cell site (Antenna) location• Phase II Calls are routed based on the callers location (XY)

• VoIP (Voice over the Internet Protocol)• I1 Calls are directed to a 10 digit administrative number at the

PSAP• I2 Calls are routed based on the callers location (XY) over

TDM• I3 Calls are routed based on the callers location (XY) over

VoIP

• Telematics, ACN OnStar, Automatic Crash Notification• Text Devices Instant messaging to the PSAP

• PDAs, Blackberry• Satellite Phones• AirPhone• Medical devices• Video

• FCC tentatively concluded that IP-enabled services, including VoIP, are Title I, information/enhanced services, and not Title II telecommunications services

• Deals with the an entire spectrum of legal/regulatory issues

– Carrier Compensation – payment of reciprocal compensation and access charges

– CALEA

– Universal Service Fund

– Disability Access

– 911

• Because of increasing public concern about 911 access by VoIP end users, the FCC culled out 911 from the broader proceeding and issued its order

• “Interconnected VoIP” providers have the capability to originate calls onto PSTN and terminate calls through the PSTN

• Applies to VoIP services in the US and its territories, whether “fixed” (by physical limitations or contractual provisions) or mobile (whether “limited mobility,” i.e., within a rate center or a SR area, or full mobility,

• In those cases where there is interconnection, and a SR, VoIP providers may not send calls to administrative lines (unlike aspects of Qwest’s C-VoIP current offering)

Requires “interconnected VoIP providers” to provide E911 information – call back information and location – to the “appropriate” PSAP - November 28,2005

NYC VoIP 911

In NYC Verizon and Intrado established a gateway connected to the 911 Selective Routers with dedicated facilities. The VoIP provider simply routes 911 calls over the

internet to the Emergency Services Gateway.
