Chapter 3. Voice Interface Configuration

After reading this chapter, you should be able to perform the following tasks:

• Configure analog and digital voice interfaces as new devices are introduced into the voice path

• Configure analog and digital voice ports for optimal voice quality

Voice gateways bridge the gap between the VoIP world and the traditional telephony world (for example, a PBX, the PSTN, or an analog phone). Cisco voice gateways connect to traditional telephony devices via voice ports. This chapter introduces basic configuration of analog and digital voice ports, and demonstrates how to fine-tune voice ports with port-specific configurations.

Upon completing this chapter, you will be able to configure voice interfaces on Cisco voice-enabled equipment for connection to traditional, nonpacketized telephony equipment.
