Customer Driven
I have been a CAB member for the past three
years and value the program completely. The LEGO
Group truly benefits from the products, services,
and actions that result from CABs. Joanne

SIP/Dynamic IP/MPLS Overview
11
Key Driver Convergence

• Organizations today are looking for strategies to
  integrate network technologies over a single
  common infrastructure.
• This trend started many years ago in the
  inter-networking area when corporate
  infrastructures began the migration of
  delay-sensitive, mission-critical Systems Network
  Architecture data traffic across an IP
  infrastructure.
• Organizations are examining their existing and
  often separate data, voice, and video network
  infrastructures and determining the most
  efficient ways of bringing these together.

12
What is SIP

• The Session Initiation Protocol (SIP) is an
  application-layer control (signaling) protocol
  for creating, modifying and terminating sessions
  with one or more participants.
• Enabler of Applications
• Will / Is revolutionize communications/media

13
What is SIP Trunking

• Direct IP Peering Between SIP-Enabled IP PBXs
  and Service Provider SIP-Enabled Networks
• Based On Mature SIP Standards
• Based On Reference Architecture Defined by
  SIPConnect Forum
• Replacement Of TDM Based Trunking Such As PRI And
  CAS Trunks
• Logical SIP Trunk Overlaying IP Network

14
SIPConnect

• Part of SIP Forum
• Defines Standard Interface Specification
• The SIPconnect Interface Specification is an
  important industry initiative that builds on
  existing IETF standards to define a method for
  interconnection between IP PBXs and VoIP service
  provider networks, and specifies a reference
  architecture, required protocols and features,
  and implementation rules necessary for seamless
  IP peering between IP PBXs and VoIP service
  providers.
• Features Benefits
• A Ubiquitous Approach. SIPconnect provides a
  common method for IP peering between SIP-enabled
  IP PBXs and VoIP service providers
• Standards Based. SIPconnect leverages existing
  SIP and related VoIP standards published by the
  Internet Engineering Task Force (IETF)
• Customer Cost Savings. Peering will lower service
  provider infrastructure cost and reduce the need
  for customer premises gateways
• Richer Feature Support. SIPconnect helps service
  providers deliver enhanced, personalized services
  to IP-PBXs and extends rich-media services
  enabled by IP-PBXs across service provider
  networks
• Quality of Service. Methods for handling QoS
  configuration, echo cancellation, DTMF relay,
  packetization rates, codec support and fax and
  data traffic are defined

15
Terminology

• RTP Real Time Transport Protocol
• Used for delivering media audio, video and DTMF
• A term you may hear is SRTP (Secure, meaning
  encrypted, RTP)
• Since PAETEC delivers RTP over a private MPLS
  network and anchors the media thru our SBCs, SRTP
  is not required nor supported.
• TLS Transport Layer Security (Encrypted SIP
  basically)
• SIP messaging could also ride across a private
  MPLS network thru SBCs.
• Compression/CODECs
• G.711, uncompressed voice (85k per call so
  roughly 16 calls per T1)
• Used for FAX and data devices primarily over VoIP
• G.729a, compressed voice (30k per call, maximum
  of 48 calls per T1) Based on DSP resources
• This is our default codec
• Story to customers (many of our competitors
  cannot support compression, XO and CBeyond. In
  order to get the same amount of calls across a
  dynamic service as traditional PRI or lines, they
  would have to deliver 2 T1s)
• Other audio codecs G.729b (not supported), G.726
  (not supported)

16
VoIP Network Components

• Gateways
• Dumb Box
• Converts between IP and TDM
• Physical Interface to TDM network
• Distributed geographically in CO
• SoftSwitch
• Tells the Gateway what to do
• Call Set-up, signaling, routing decisions
• Centrally located (1 Softswitch support multiple
  gateway locations)
• Application Servers (Broadsoft)
• Provide intelligent applications (voicemail,
  Centrex, Conferencing, etc)
• Centrally Located

• Session Border Controller
• Firewall that understands VoIP
• Distributed geographically in CO
• Routers
• Interface to data Network
• Remote access for maintenance
• Distributed geographically in CO

17
SIP Trunking Benefits

• Cost Savings
• Gateways Can Be Eliminated (customer, provider
  still needs them)
• Increased Number of Simultaneous Calls per T1
• Up to 50 Simultaneous Calls with Compressed Codec
• Better Voice Quality
• End to End QoS
• Lower Latency and Echo Due To The Removal of
  TMD-IP Conversion
• Enables IP Overlay Services
• Presence
• Unified Messaging
• Converged Voice And Data Into A Single IP Pipe
• Guaranteed Voice Bandwidth
• Dynamically Allocated Bandwidth for Data
• Provides A Web-based Control Panel That Can Be
  Used To Make Changes Instantly To Your Features
  And Call-handling Behavior

18
Dynamic IP Differences

• All VoIP is not the same
• The difference
• Voice over IP using T-1and above
• Not voice over Internet
• Voice QoS via the traditional voice network
• Dynamic bandwidth allocation
• True bandwidth throughput
• Works with Key, TDM, and SIP key systems, or PBXs
• IP Hosted Telephony

Private-IP MPLS Benefits

• Allows for full port speed
• No Committed Information Rate (CIR) No
  discard-eligible traffic
• No Committed Access Rate (CAR) (i.e. MPLS over
  ATM/Frame)
• No need to manage PVCs CIRs
• Automatically meshes the network
• Automatic re-routing via IP
• Ability to prioritize data applications
• Traverses over a Private-IP, not a cell-based
  network
• Access the corporate network remotely
• Reduces monthly network costs

31
SIP Trends

• SIP Trunking Experience
• Active deployments with CPE providers such as
  Toshiba, Cisco, Avaya, Allworx, Asterisk,
  Shoretel, Mitel, and Nortel to name a few.
• G.711 or G.729 offered
• SIP Trunking over Ethernet (another trend)
• 10Mbps to 1Gbps Ethernet Loops available
• SIP Trunking Shared with MPLS a requirement.
• Dedicated Access Loops/Not Oversubscribed
• QoS allows proper engineering of voice traffic
  for assured quality.
