Verifying Voice Ports

• Check for dial tone (FXS only).

• Check for DTMF tones (FXS only).

• Use the show voice port command to check the configuration.

• Use the show voice port command to ensure that the port isenabled.

• Be sure that the PBX configuration is compatible with the voiceport.

• Check the physical installation of the hardware.

Summary

Voice ports on routers and access servers emulate physicaltelephony switch connections.

Analog voice port interfaces connect routers in packet-basednetworks to analog two-wire or four-wire circuits in telephony

networks. FXS, FXO, and E&M ports have several configuration

parameters.

8/14/2019 CVOICE 6.0 S02 L02



Summary (Cont.)

CAMA is used for 911 and E911 services.

DID service enables callers to dial an extension directly on a PBXor packet voice system.

You can set a number of timers and timing parameters for fine-

tuning the voice port.

The show, debug, and test commands are used for monitoringand troubleshooting voice functions in the network.
