work
• Pick up any phone
– even “disconnected” phones
• Dial 9-1-1
• Public Safety Answering Point (PSAP) answers
– Sees phone # and exact location
• Appropriate first responders dispatched
• Help arrives in a timely manner
• Everyone lives happily ever after9-1-1 • Started in 1968 • Connects the caller to the local police station • Did not identify caller or location • Provided P id d access tto emergency services i
Enhanced 9-1-1 (E911)
• Started in 1970
• Connects the caller to a Public Safety Answering Point
(PSAP)
– Associates a physical address with the calling party's telephone

number, and

– The source number is used to look up the Emergency Service
Number (ESN) of the appropriate call center (PSAP) in a
database and connect the call
• Provides access to the caller location information (CLI)
of emergency calls
– Street map display
– Nearest available emergency responders
– Other relevant information (fire hydrants, hazardous materials,
etc.)Enhanced 9-1-1 (E911)
• A caller's telephone number and location
information is gathered by mapping the calling
phone number to an address in a database
– Automatic

• The database is generally maintained by the
local telephone company
company, under a contract with
the PSAP
• Each telephone company has its own standards
for the formatting of the databaseVOIP and 9-1-1
• Call routing established by service provider
– May go to a non-emergency number at the PSAP
based on billing or service address
– May not go anywhere at all
• A VOIP adapter
d t can be b plugged
l d iinto
t any
broadband internet connection
– The caller could be thousands of miles away from the
billing address - not the actual location of the callVOIP and 9-1-1
• Most VOIP users who dial 9-1-1 are connected to a call
center owned or contracted by their provider
• The operators are there to connect the caller to the
appropriate emergency service or PSAP, usually one in
th generall area
the
• A 9-1-1 operator at that PSAP must then determine the
location of the emergency,
g y, and either send help
p directly,
y,
or transfer the caller to the appropriate PSAP
– In April 2008, an 18-month-old boy in Alberta died after a VoIP
provider's 9-1-1 operator had an ambulance dispatched to the
family's previous address in OntarioApplicable Ordinances
VOIP and 9-1-1
• In March 2005, a commercial Internet telephony
provider was sued by a state attorney general,
alleging they did not make it clear enough that
the provision of 9
9-1-1
1 1 service was not done in
the traditional manner
• In May 2005, the FCC issued an order requiring
VoIP providers to offer 9-1-1 service to all their
subscribersApplicable Ordinances
• Wireless Communications and Public Safety Act
of 1999
– VoIP E911 is not required; customers may opt-out
VoIP E911 information is only accurate if subscribers are
diligent
– Burden of responsibility upon the subscribers and not
the providers
• Communications Assistance for Law
Enforcement Act of 1994
– Lumped common carriers, facilities-based broadband

• In 2005, the FCC issued “E911

Providers”, requiring providers to:
– Provide Enhanced 911 service
– Disclose anyy limitations on their E-911
functionality to their consumers
– Obtain affirmative acknowledgements

these disclosures from all consumersApplicable Ordinances

• E911 locates building
– Relies on individual (representative) to identify to
locate actual space
– Requirements for a building representative
How many do you assign/train?
How do you ensure one is available at all times?
How do they get the phone location (office) information?
How do you ensure it is accurate?
– Advise employees that “we
we may not be able to find
you”
Labels on phones?Legacy PBX
• Commercial buildings with traditional landline
phones
– E911 can identify main extension and maybe building
location
– Gets first responders to the main entrance
– Need local representative to find specific location
Relies on multiple communication efforts

• Locations are assigned to the outlet at the patch
panel
• Phone numbers stay at the outlet and don’t
follow the phone
– Phones are unassigned devices and are considered
mobile
• Easier to control the process of changing the
phone number
– PBX personnel familiar with the process
– Lines that are moved require

g with VOIP Phone
Systems
VOIP systems need upfront programming
Zone IP addressing
Since phone numbers stay with the IP phone,
VOIP phones need to stay in assigned locations
Zone control of IP, subnet and patch assignments
to switch ports require more regulated
administration to change locations
Unlike traditional phonesVOIP PBX
• Phones are assigned devices
– But

• Locations are not assigned
– Mayy be tracked in a database
• Phone numbers are assigned to the VOIP
device
– If the phone moves
moves, the number moves
• Phone is not tied to a specific location
– Location ((90 feet)) is determined byy the IP address,
not the phone
• Building representative may still be necessaryVOIP PBX
• Traditional E911 Solutions for VOIP
– Quadrant assignment and dedicated port patching
Inefficient use of IP addresses (switches)
Dedicated port patching by ‘zone’
zone
More complexity in IP addressing – none of it is standardized
Reduces efficiency of VOIP system
– Lock down the floor - only specific subnets are
assigned to IP addresses
– Separate switchgear for VOIP system
• Only helps to generalize the locationHow can you find the IP Phone

• Manual database
– Moves and add-ons still require manual

• IP Address and Zone Management

levels of Integration
– Full Integration: Software to Software
– Data Integration: Data pushed to VOIP Mgmt
– Manual Look-up: Stand-alone IIM
• Information can be shared:
– In real time as the VoIP asset moves
– On-demand when the 911 call is made
– Physically on manual look-up (Drawing or escort)

driven by a number of factors
– E911 Call center technology gy
– VOIP Management Platform
– IIM System software
– Site specific labeling of Phones, Outlets,
offices,, etc.
– Cost of integration

– Company response personnel receive notification

• How? Processes range from:

– VOIP PBX queries IIMS database with MAC address
– The IIM System sends an alert (screen pop
