Hi David, were you able to see the received fax in the extension's web portal or app?

Thanks Anirban, but I tried all of this before submitting my original message. But thanks for making the suggestions!!!

RC has a gremlin running amok in their fax routing - we've had this issue since February as well.
Their 'workaround' is to put the email address in the authorized to send email - even though it should be from the same email address - sometimes it just 'forgets.'

Under Outbound Calls/Faxes - Fax Settings - at the bottom.
Add the same email address to that field and save... send a test.
