R0106-HP MSR Router Series Layer 2 - WAN Command Reference(V7)

246
Parameters
remote-number: Specifies an ISDN calling number, a case-insensitive string of 1 to 30 characters. The
asterisks (*) represent any characters.
callback: Enables callback for the specified ISDN calling number.
Usage guidelines
When receiving a call, the device with the dialer call-in command configured first verifies that the caller
is valid before processing the call. If the remote SPCS does not provide the calling number, the call is
dropped directly.
On a dialup interface configured with the dialer call-in callback command, you must configure the
corresponding dialer route or dialer number command. The dial-number configured in the dialer route
or dialer number command must be the same as the remote-number configured in the dialer call-in
command.
Examples
# Configure the device to place return calls for ISDN calling number 8810152.

[Sysname-Bri2/4/0] dialer route ip 100.1.1.2 8810152

Usage guidelines
DDR includes traditional DDR and bundle DDR.
Before using traditional DDR, you must use this command to enable traditional DDR on the dialer
interface.
If you configure this command on a dialer interface already enabled with bundle DDR, the system clears
the original bundle DDR configuration.
The undo dialer circular enable command clears all DDR configurations on a dialer interface.
