Parameters
caller-number: Specifies an acceptable calling number, a case-sensitive string of 1 to 24 characters.
Usage guidelines
Calling number verification enables an ISDN interface to accept only calls from a specific calling party.
Call setup will fail in the following situations:
• The calling number in the incoming SETUP message is not configured on the ISDN interface.
• The incoming SETUP message does not include a calling number.
Examples
# Configure the interface BRI 2/4/0 to accept incoming calls only from the calling number 400.
<Sysname> system-view
[Sysname] interface bri 2/4/0
[Sysname-Bri2/4/0] isdn caller-number 400
