Displaying the Status of ISDN Calls
Purpose
Display the status of ISDN calls. This information helps you to verify the dialer interface configuration as described in Verifying Dialer Interface Configuration. The command also provides a list of the B-channels configured on an ISDN BRI or ISDN PRI interface.
Action
From the CLI, enter the show isdn calls command.

Meaning
The output shows a summary of B-channel interfaces and the active ISDN calls on the interfaces. The first example shows the two B-channels on an ISDN BRI interface—bc-2/0/0:1 and bc-2/0/0:2. The second example indicates B-channels bc-2/0/0:1 through bc-2/0/0:23, the 23 B-channels on an ISDN PRI interface. Determine the following information:
- The interfaces on which ISDN calls are in progress
- Whether the call is a dial-in call, dial-out call, or a callback call
