Reduce tedious tasks of sending fax one by one
If you see the Fax API here: https://developers.ringcentral.com/api-reference/Fax/createFaxMessage
there is an array in the request, To field where the Fax message will be send
This array is the collection of phone numbers where the Fax will be send automatically at a same time.
So, you don't need to repeat the Fax API call one by one to send to each number
