    1. VoIP Signaling and Call Control Cisco Networking Academy Program

    2. Need for Signaling and Call Control Thanks for joining us today to attend the Cisco Brand and Corporate Identity Workshop. In the first half of the workshop I am going to cover Brand Matters and talk in detail about the Cisco brand, and in the second half my colleague Gary McCavvit is going to take you through our updated visual identity system. At the end of the workshop we’re going to leave some time for a fun quiz as well as some Q&A.Thanks for joining us today to attend the Cisco Brand and Corporate Identity Workshop.

    44. MGCP and Associated Standards MGCP is defined in RFC 2705, October 1999 MGCP architecture and requirements are defined in RFC 2805, April 2000 Centralized device control with simple endpoints for basic and enhanced telephony services Allows remote control of various devices Stimulus protocol Endpoints and gateways cannot function alone Uses IETF SDP Addressing by E.164 telephone number

    45. MGCP Components

    46. Endpoints Eight types of endpoints are defined in RFC 2705: Digital channel Analog line Announcement server access point IVR access point Conference bridge access point Packet relay Wiretap access point ATM trunk side interface

    47. Endpoint Identifiers

    48. Gateways and Their Roles Trunk gateway SS7 ISUP Trunk gateway MF NAS Combined NAS/VoIP gateway Access gateway Residential gateway Announcement servers

    49. Call Agents

    50. Basic MGCP Concepts Calls and connections Events and signals Packages and digit maps

    51. Calls and Connections

    52. Multipoint Calls

    53. Events and Signals Events: Continuity detection (as a result of a continuity test) Continuity tone DTMF digits Fax tones Hookflash Modem tones Off-hook transition On-hook transition

    54. Events and Signals (Cont.) Signals: Answer tone Busy tone Call waiting tone Confirm tone Continuity test Continuity tone Dial tone Distinctive ringing (0…7) DTMF tones Intercept tone Network congestion tone Off-hook warning tone Preemption tone Ringback tone Ringing

    55. Packages Basic packages (generic media, DTMF, MF, trunk, line, handset, RTP, NAS, announcement server, script) CAS packages (RFC 3064) Business telephone packages (RFC 3149)
