Whitelist Only Phone Numbers

[PBXMePlz]

I'm looking at playing with an option to whitelist only certain phone numbers, and hopefully have a relatively easy way to whitelist it.
I've been looking at call flows which would be great, but I only have true/false variable to play with.
It looks like I could maybe work on inbound routes, and set a condition for source possible.
Thoughts on how to best implement this?

I have created an inbound route for this (see below, sanitized).
It basically a IF-THEN-ELSE statement using the action and anti-action statements.
Key points are the <condition field="caller_id_number" expression="^(?:\+1|1)?(##########|##########|##########)$">
This does a REGEX lookup to see if the caller_id_number is authorized.
I'd like this to use LUA and a database lookup, although this would be a lot of programming to create.


<extension name="##########" continue="false" uuid="UUID">
<condition field="destination_number" expression="^(##########)$"/>
<condition field="caller_id_number" expression="^(?:\+1|1)?(##########|##########|##########)$">
IF-Then
<action application="export" data="call_direction=inbound" inline="true"/>
<action application="set" data="domain_uuid=UUID" inline="true"/>
<action application="set" data="domain_name=XX.XX.XX.XX" inline="true"/>
<action application="set" data="hangup_after_bridge=true"/>
<action application="set" data="continue_on_fail=true"/>
<action application="transfer" data="########## XML XX.XX.XX.XX"/>
<action application="set" data="voicemail_action=save"/>
<action application="set" data="voicemail_id=##########"/>
<action application="set" data="voicemail_profile=default"/>
<action application="set" data="domain_name=XX.XX.XX.XX"/>
<action application="set" data="domain_uuid=UUID"/>
<action application="set" data="send_to_voicemail=true"/>
<action application="lua" data="app.lua voicemail"/>
<action application="hangup" data=""/>
ELSE
<anti-action application="set" data="voicemail_action=save"/>
<anti-action application="set" data="voicemail_id=##########"/>
<anti-action application="set" data="voicemail_profile=default"/>
<anti-action application="set" data="domain_name=XX.XX.XX.XX"/>
<anti-action application="set" data="domain_uuid=UUID"/>
<anti-action application="set" data="send_to_voicemail=true"/>
<anti-action application="lua" data="app.lua voicemail"/>
<anti-action application="hangup" data=""/>
</condition>
</extension>
