    Chapter 8. Infrastructure Protocols

    Chapter 8. Infrastructure Protocols

    Although voice signaling and media transport protocols, such as MGCP, H.323, SIP, SCCP, and RTP, are essential, other generic infrastructure protocols, such as DNS, TFTP, NTP, and Power over Ethernet (PoE), are also required in order for a telephony network to operate properly.

    DNS, TFTP, NTP, and PoE are discussed in this chapter.
