Use the show voice port command to check the configuration. 4. Use the show voice port command to ensure that the port is enabled. 5. Be sure that the PBX configuration is compatible with the voice port. 6. Check the physical installation of the hardware.

© 2006 Cisco Systems, Inc. All rights reserved. CVOICE v Summary Voice port applications include local, on-net, off-net, PLAR, PBX to PBX, Cisco CallManager to Cisco CallManager, and on-net to off-net calls. Configurable parameters on FXS ports include signal, cptone, description, ring frequency, ring cadence, disconnect- ack, busyout, station id name, and station id number. Configurable parameters on FXO ports include signal, ring number, dial-type, description, and supervisory disconnect. Configurable parameters on E&M ports include signal, operation, type, auto-cut-through, and description.

© 2006 Cisco Systems, Inc. All rights reserved. CVOICE v Summary (Cont.) Configurable timer and timing parameters define initial digit and interdigit timing, digit and interdigit duration, and ringing time. Digital voice ports are created with the ds0-group command in the T1/E1 controller. ISDN configuration requires that the pri-group command specify timeslots used for voice and signaling. T-CCS allows for the transparent passing of proprietary PBX signaling across the IP network. The show, debug, and test commands are used for monitoring and troubleshooting voice functions in the network.
