Displaying the Active Call Information

Enter the show port voice active command to display the active call information on a port. There are up to 8 calls per port for the 8-port T1/E1 PSTN interface module but only one call per port for the 24-port FXS analog station interface module.

To display the active call information, perform this task in normal mode:

Task

Command

 

 

Display the active call information.

show port voice active [mod/port]

 

[all call conference transcode] [ipaddr]

 

 

Entering the show port voice active command without any parameters shows all the calls in the system (regular calls, conference calls, and transcoding calls). The display field descriptions are as follows:

Type—The “call” notation is for the 24-port FXS analog interface module and 8-port PSTN interface module calls.

When you configure the 8-port T1/E1 PSTN interfaces for transcoding and/or conferencing, the Type field displays “conferencing” for conferencing calls and “transcoding” for transcoding calls.

Conference-ID, Transcoding-ID, and Party-ID are applicable only to the 8-port T1/E1 PSTN interfaces that are configured for transcoding and/or conferencing.
