  2. Agenda • What is SIP? • Why SIP over T1/PRI? • SIP Trunking • Cisco SIP End points

  3. Agenda • What is SIP? • Why SIP over T1/PRI? • SIP Trunking • Cisco SIP End points

  4. What is SIP? • Session Initiation Protocol (RFC 3261) • SIP uses Text based commands • SIP User Agent (UA) • SIP User Agent Client (UAC) & User Agent Server (UAS) • Session Border Controllers

  5. SIP • The Session Initiation Protocol (SIP) is an IETF-defined signaling protocol, widely used for controlling multimedia communication sessions such as voice and video calls over Internet Protocol (IP). • SIP clients typically use TCP or UDP on port numbers 5060 and/or 5061 to connect to SIP servers and other SIP endpoints

  14. Session Boarder Controller • The Cisco Unified Border Element (CUBE) facilitates simple and cost-effective connectivity between enterprise unified communications Session Initiation Protocol (SIP) trunks to the public-switched telephone network (PSTN). Designed to meet enterprise and service-provider Session Border Controller (SBC)

  15. IOS Gateway Configuration • SIP configuration is similar to H.323 • SIP uses Dial Peers dial-peer voice 2 voip destination-pattern 8... session protocol sipv2 session target ipv4:9.13.8.16 dtmf-relay rtp-nte

  16. IOS Gateway Configuration • SIP-UA section used if authentication is required sip-ua registrar ipv4:200.1.1.10 or registrar dns:csps.cisco.com authentication username xyz password xyz realm cisco.com

  17. IOS Gateway Configuration • Voice Service VoIP voice service voip allow-connections h323 to sip allow-connections sip to h323 allow-connections sip to sip allow-connections h323 to h323

  18. UCM Configuration • Build CUBE and SIP Gateways as Trunks

  19. UCM Configuration • Build CUBE and SIP Gateways as Trunks

  20. Agenda • What is SIP? • Why SIP over T1/PRI? • SIP Trunking • Cisco SIP End points

  21. Why SIP over T1? • Increased Capacity • One 10MB SIP trunk equals 5.3 T1s • Added Features over T1 • SIP trunks can carry voice, video and application information • Quicker to Increase Capacity • Increasing capacity is just a software setting

  22. Why SIP over T1? • Increased Capacity • One 10MB SIP trunk equals 5.3 T1s • Added Features over T1 • SIP trunks can carry voice, video and application information • Quicker to Increase Capacity • Increasing capacity is just a software setting

  23. Agenda • What is SIP? • Why SIP over T1/PRI? • SIP Trunking • Cisco SIP End points

  24. SIP Trunking • SIP trunking is becoming more available from Telco Vendors like Triad Telecom. • Deployment models vary from MPLS connections to Dedicated circuits to Internet connections. • Cisco is using Internet connections with their Intercompany Media Exchange (IME)

  25. Agenda • What is SIP? • Why SIP over T1/PRI? • SIP Trunking • Cisco SIP End points

  26. Cisco SIP • 794X/6X phones are SCCP and SIP capable • 8961 and 99XX are SIP only devices • Cisco 2800/2900/3800/3900 IOS gateways can be SIP gateways • TelePresence Units • Unity, Unity Connection and Unity Express • MeetingPlace and MeetingPlace Express
