The scenario is that a "site" has a physical fax machine with an attached Cisco ATA. Standard inbound and outbound faxing from the device works as expected. We would like to designate that fax machine as the main "fax number" for that specific site, so that the associated users in that site can also be assigned that phone number as their OUTBOUND fax number. This process would centralize all received faxes to come out at the physical device, but allow sending of faxes from both the machine, and electronically from any user in the site with the RingCentral app available to them.
