CHAPTER 14

  • PSTN and VoIP Interworking
Voice over IP Fundamentals
slide2

Cisco Packet Telephony:

  • Connection Control
  • Call Control
  • Services
slide3

Cisco Packet Telephony:

  • Connection Control
    • Functionally sets up, maintains and tears down the call
    • Uses AS5850, MGX 8850, 2600, 3600, and 3810
    • Communicates with the Call Control Plane via Media Gateway Control Protocol (MGCP)
slide4

Cisco Packet Telephony:

  • Call Control
    • Functionally signals, processes and route voice calls
    • Uses Signaling System Seven (SS7)
    • Processes include digit analysis and manipulation, route selection, hunting, and switch-based features
    • Interfaces with external logic programs
    • Uses or can use: MGCP, SIP, H.323, and MEGACO
    • Call Control plane is unknowing of the VoIP system and is there for transport
    • Can interact with IP, , ATM, Frame-relay….
