subaddress: Subaddress, which is a string comprising digits and/or case-insensitive
English letters and is 1 to 20 characters in length.
Description
Using the isdn check-called-number command, you can configure the called
number or subaddress that the system should verify when receiving a digital call.

configuration.
By default, the system does not check the called number or subaddress carried by

calling party sends a wrong subaddress or does not send at all.

Check whether the called number carried by incoming digital calls is 66668888 on
the interface Bri 0/0/0.
