Dialer Circular Enable - H3C MSR Series Command Reference Manual

Parameters
remote-number: ISDN calling number, a case-insensitive string of 1 to 30 characters. The asterisks (*)
represent any characters.
callback: Enables the device to place a return call if an ISDN calling number matches the number
specified by the remote-number argument (starting with the rightmost character).
Usage guidelines
When receiving an incoming ISDN call, the device with the dialer call-in command configured first
verifies that the caller is valid before processing the call. If the remote PBX does not provide the calling
number, the call is dropped directly.
On a dialup interface (physical or dialer interface) configured with the dialer call-in callback command,
you must configure the corresponding dialer route command or dialer number command, making sure
that the dial-number configured in the dialer route or dialer number command is 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> system-view
[Sysname] interface bri 1/0
[Sysname-Bri1/0] dialer route ip 100.1.1.2 8810152
[Sysname-Bri1/0] dialer call-in 8810152 callback
