EXEC
Release	Modification
11.3(1)MA	This command was introduced for the Cisco MC3810 multiservice
	concentrator.
12.0(7)XK	This command was first supported on the Cisco 2600 and 3600 series.
12.1(2)T	This command was integrated into the 12.1(2)T release.

The show voice call command applies to Voice over Frame Relay, Voice over ATM, and Voice over IP.

This command shows call-processing and protocol state-machine information for a voice port, if it is available. It also shows information on the DSP channel associated with the voice port, if it is available. All real-time information in the DSP channel, such as jitter and buffer overrun for example, is queried to the DSP channel, and asynchronous responses are returned to the host side.

If no call is active on a voice port, the show voice call summary command displays only the VPM (shutdown) state. If a call is active on a voice port, the VTSPS state is shown. For an on-net call or a local call without local-bypass (not cross-connected), the CODEC and VAD fields are displayed. For an off-net call or a local call with local-bypass, the CODEC and VAD fields are not displayed.

CODEC and VAD are not displayed by the show voice call command because this information is in the summary display.
