Caller ID for Outbound Calls shows Unknown as the name and the number 20 as the number even though the extension calling out isn't even the number 20.

This is a call, from your PBX, to an outside number? Is this for all outbound calls? If that is the case (in most cases a provider won't complete calls if the caller ID is not in a PSTN standard format), then first check the outbound rules , to see if the number 20, has been put into the Caller ID settings, for that rule. If not, then you may have to make use of the Activity Log (verbose) to see what might be happening.

If you can't figure out what settings are causing this, please also let us know what SIP Provider you're using and if it's a 3CX Supported one.

Also, should the issue persist, try setting the Outbound Caller ID of the Outbound Rule to the correct caller ID, does that change anything?
