Command History
Usage Guidelines Use the show voice port EXEC command to display configuration and voice-interface-card-specific
information about a specific port.
This command applies to Voice over IP, Voice over Frame Relay, and Voice over ATM.
The ds0-group command automatically creates a logical voice port that is numbered as follows on Cisco
7200 series routers and the Cisco 2600 and Cisco 3600 series routers: slot/port:ds0-group-no. Although
only one voice port is created for each group, applicable calls are routed to any channel in the group.
Examples The following is sample output from the show voice port summary command for all voice ports on a
Cisco MC3810 multiservice concentrator with an analog voice module (AVM):
IN OUT ECHO
