Default command level
2: System level
Parameters
remote-number: Used for matching ISDN calling numbers, a 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.
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 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.
