We were having trouble receiving faxes from certain vendors/customers. RC support said problem was on senders end, but come to find out they were being blocked as Robocalls by RC for us. To see if this is true for you, log into RC desktop app under the extension that is assigned the Main Company Fax # and look under calls. If you see "Suspected Robocall" a bunch of times from the sender's fax # this is your problem. To fix (as of Oct. 2023 hopefully - we'll see) had to disable robocall blocking under Users>users with extensions>click main company admin user>Phone>Blocked Calls>Robocalls>Block option... Change this to "Ring devices and apps" from "Play message and disconnect." Hope this helps! We were getting the runaround from everyone and it was a real pain.
