Voice ports are found at the intersections of packet-based networks and traditional telephony networks,
and they facilitate the passing of voice and call signals between the two networks. Physically, voice ports
connect a router or access server to a line from a circuit-switched telephony device in a PBX or the public
switched telephone network (PSTN).

Basic software configuration for voice ports describes the type of connection being made and the type
of signaling to take place over this connection. Additional commands provide fine-tuning for voice
quality, enable special features, and specify parameters to match those of proprietary PBXs.

This chapter includes the following sections:

Not all voice-port commands are covered in this chapter. Some are described in the “Configuring Trunk
Connections and Conditioning Features” chapter or the “Configuring ISDN Interfaces for Voice” chapter
in this configuration guide. The voice-port configuration commands included in this chapter are fully
documented in the Cisco IOS Voice, Video, and Fax Command Reference.
