SIP - Ready to Deploy

• Jim Nelson, Co-CEO

3
Industry Mandates

• A Robust Connection Management Platform Which
• Interoperates
• Scales
• Is extendable
• Enables applications

4
SIP - The Killer App

• Developed in mmusic Group in IETF
• Proposed standard - RFC2543
• Protocol for Session Invitation and Connection
  Management
• Protocol Strengths
• Highly scalable
• Uses established Internet protocols
• Media and transport independent
• Enables applications
• Highly secure

5
Two Key Components - Agents

• User Agent Client - UAC
• Initiate SIP Requests
• User Agent Server - UAS
• Accepts or Rejects call
• Reside in
• Softswitches
• IP and soft phones
• Handheld and wireless devices
• DSL/Cable equipment
• PBX/UnPBX

6
Two Key Components - Servers

• Proxy Server
• Heart of SIP network which contains all service
  logic
• Redirect Server
• Returns routing information to the initiating
  endpoint
• Registration
• Registration enables subscriber mobility

7
SIP Server Controls Service Logic

• Primary Place for SIP Services
• Controls all service logic
• Central point for location and billing services
• Internet Integration
• SIP integrates with web, email and chat
  applications
• Call Processing Language
• XML language for creating services and
  applications

8
Where Should SIP Servers Reside?

• Service Provider Networks
• ITSPs
• Long distance carriers
• Cable MSOs
• Firewalls
• Network address translations
• Network Access Points
• Cross network interoperability

9
SIP Is Interoperable

• 2 Successful Bake-offs
• 15 companies
• Began with basic call set up (2 Vendors)
• Elevated testing to more advanced features such
  as authenticated registrations, multi-hop proxy
  and media transport
• Communication Between Endpoints
• Two vendor demo - PingTel
• Moving Forward with Interop Testing
• Bake-off needs to focus on three-way testing
  between vendors to better model the needs of a
  commercial network

10
SIP is Scalable

• SIP Scales to the Internet
• HTTP server comparison
• Documented SIP Performance Exists
• Ability to scale to 500,000 BHCA
• Moving Forward with Scalability
• Develop performance benchmark
• Continued SIP performance from multiple vendors
  to eliminate any speculation that SIP is ready
  for deployment NOW

11
SIP is Extendable

• SIP-T - SIP for Telephony Interworking
• SIP for intra-softswitch communications
• Allows for the bridging of the PSTN and IP
  networks
• CPL - Call Processing Language
• Network edge service creation
• Allows for the Proxy Server to handle service
  requests
• DCS - Distributed Call State
• SIP for cable telephony
• Allows for service intelligence to be
  decentralized

12
SIP Is Deployable Today!
13
All This Leads to Applications

• Follow-me
• Mobility
• Internet Call Waiting
• Unified Messaging
• Call Center
• Web/Email Integration

14
SIP Momentum

• Softswitch to Softswitch Communication Using
  SIP-T
• Level (3)
• DCS - Cable Industry Support Distributed Call
  Signaling Using SIP
• Packet cable initiative
• Vendors and Service Providers are Now Choosing
  SIP
• Softswitches (MGC), gateways, endpoints,
  application servers
• SIP-based networks and services (MCI, Level(3),
  ATT)
