notes: I've redacted the last part of the numbers for privacy but in this example 01934xxxxxx is my real home number which is the extension that the FXO adaptor dials on incoming calls, 07970xxxxxx and 01202xxxxxx are examples of numbers I want whitelisted you can just duplicate this line for each number on your whitelist.
1000, 1001, 1002 and 2000 are my SIP extensions that I want the allowed calls to ring
