We're working on an application that will send and receive faxes via the RingCentral API.
Let's assume that a our client already has an RC account and is using it for its purposes.
As the client is going to work with our application, they need to get a few fax lines among all their.
Could you please explain how it is possible to limit the scope of the API to get only those faxes from a few fax lines?
