Test the “Caller-Network-Addr” channel variable, although I am not certain if you should use hyphen - or underscore _ as they have different meanings in FS.
You can test any FreeSWITCH channel variable as a condition in the dialplan, not only the destination_number.
To find the proper variable, create a dialplan record that executes the “info” dialplan app and then call that extension:
<action application="info"/>
This will display all channel variables associated with that call on the fs_cli console.
Here is the link to the wiki article about the info app:
