I have the instructions from the knowledge base:

But the fax line for the site I am trying to configure is not an available option. How do I make it appear in the list?

Have you checked if the number is a Fax Number?
Go to Phone System > Phone Numbers > All Numbers.
Take note that numbers assigned to other extensions can't be used as your Outbound Fax Caller ID.
Are you the admin on the account?

It is assigned to the fax line's extension. Can I not make other user's outbound caller ID show as the main inbound number?
