Voip in public safety l.jpg
VoIP in Public Safety

  • There are an estimated 2.5 million residential VoIP customers just in the United States

  • This number is expected to grow to 9 million by 2008

  • Only about 1/3 have 9-1-1 service!

  • Those that do may not have their calls properly routed to the 9-1-1 lines, and most do not have location information attached

  • VoIP is growing considerably throughout the world


Voip in public safety3 l.jpg
VoIP in Public Safety

  • Residential VoIP users

    • Millions of users right now!

    • 9-1-1 calls are converted to TDM and connected to the PSTN by the VoIP providers and then routed to the PSAP

  • VoIP used for admin lines in the PSAP

    • This is prevalent in new or consolidated centers

    • Since they are already going to install a LAN, sometimes it is more cost-effective to use VoIP phones

    • Hampshire Constabulary

  • All-VoIP PSAPs

    • Greater Manchester Police and Cheshire in the UK are all-VoIP PSAPs!

    • Inbound 9-9-9 calls are still routed to the PSAP as TDM, then converted at the PSAP to VoIP

  • All-VoIP all-over

    • Eventually, VoIP will likely replace TDM

    • PSAPs will be taking all calls via VoIP

    • This is many years into the future, due to technological as well as fiscal challenges


Voip challenges l.jpg
VoIP Challenges

  • Residential VoIP users

    • Not all calls are properly routed to the emergency lines

    • Even fewer have proper location information (ANI/ALI)

  • VoIP used for admin lines in the PSAP

    • PSAP infrastructure and vendors may have difficulty supporting a mixed telephony environment (TDM and VoIP)

    • VoIP is complicated

  • All-VoIP PSAPs

    • VoIP is complicated!

    • Lack of VoIP experience with PSAP equipment providers

    • Funding

  • All-VoIP all-over

    • Funding

    • Smooth transition from TDM to VoIP will be challenging

Funding!


Ip and voip basics l.jpg
IP and VoIP Basics

  • Internet Protocol is a set of protocols that enables file sharing, shared printers, email, the www, and various other applications

  • Voice over IP (VoIP) is the transport of voice traffic by using IP

    • Does not automatically mean Voice over the Internet

    • Currently, the internet is not structured for controlled access and bandwidth, which could affect Quality of Service (QoS)

  • IP means that traffic is broken into small packets, or sections of data, to be routed individually

  • Each packet has a header with various information, including the destination address

Why voice over ip l.jpg
Why Voice over IP?

  • Lower equipment cost – replace proprietary switches with open interface PCs and network equipment

  • Lower cost of ownership – lower maintenance costs

  • Integration of voice and data applications – people want to communicate in many ways

  • Circuit switching is excellent for voice, but is expensive and is not well-suited for anything else

  • Administration of MAC (Moves, Adds, Changes) is very easy and no cabling involved

  • Lower bandwidth requirements – greater compression options

  • Supports user mobility

  • Widespread availability of IP – it is practically everywhere

VoIP Basics: Key Terms and Concepts

  • PSTN – Public Switched Telephone NetworkFor example: MCI, British Telecom, Telefonica, NTT…

  • Voice Gateway – Converts PSTN trunks to IP

  • Call Control and Admin – “brain”, “map”, “manager”… (a.k.a soft-switch, CallManager, Media Server…)

  • VoIP Audio

    • The actual voice converted to IP packets

    • RTP (Real Time Protocol)

    • Compression (G.711, G.729, G.723.1)

  • VoIP Signaling Protocols

    • Used to initiate VoIP calls

    • H.323 (used by Avaya)

    • Skinny (Cisco proprietary)

    • UniStim (Nortel proprietary)

    • SIP (Session Initiation Protocol)

  • IP phones are simply connected to the LAN(Local Area Network)

VOIP IN PUBLIC SAFETY

Recording VoIP


Voip recording methods l.jpg
VoIP Recording Methods

Traditional recording for IP environments:

  • Traditional trunk-side tapping

  • Traditional, using observation

    VoIP recording:

  • Passive VoIP recording

  • Active VoIP recording

Note: Not all methods are available with every VoIP telephony vendor


Trunk side recording l.jpg
Trunk-side Recording

  • Loggers tap the trunks connected to the enterprise

  • Only external calls (in/out) recorded

  • Can record all phone types

  • Investment protection when migrating or adding IP phones in a traditional environment

  • Does not support migration to IP trunks

  • Available with all traditional vendors

Recording using observation l.jpg
Recording using Observation

  • Suitable mainly for QM recording

  • Loggers connect directly to the gateway

  • Utilizes silent observationmethods to obtain the audio

  • Available with Alcatel, Aspect, Avaya, Nortel, Siemens

  • Can record all phone types

  • Investment protection when migrating or adding IP phones in a traditional environment

  • Mono recording only (no analytics)

  • Limited scalability

Passive voip recording l.jpg
Passive VoIP Recording

  • Recording based on network switch mirroring / “sniffing” (SPAN)

  • Available with all vendors

  • Records external andinternal calls

  • Records only IP phones

  • Overhead for the network administrator due to requirement for mirroring in all switches

Active voip recording l.jpg
Active VoIP Recording

  • A replica of the audio is sent to the Logger by either the gatewayor the IP phones

  • Enables centralizedrecording of a distributed environment

  • Examples: Avaya CMAPI, Nortel Duplicate Media Stream, Cisco conference-based recording (others will be introduced in 2006)
