Chapter 12. Other Packet Voice Alternatives
VoIP is not the only way to transport voice traffic over non-telephony networks. Indeed, there are two alternatives discussed in this chapter that are efficient, fast, and can yield toll-quality signals at a reasonable cost. They are voice over Frame Relay (VoFR), and voice over ATM (VoATM).[1] A third alternative, voice over Ethernet, was explained in Chapter 9, as H.323 which runs on local area networks.
