sounds like a bug.
You could try one of the following to see if it affects the behavior:
1. in the app > Settings > Phone > Incoming call rules > Incoming calls > If no one answers > Play announcement
This will remove the voicemail for the user, are you still getting voicemails generated?
2. what number are you using to receive the fax?
a. Company fax number
b. digital line/ direct number of user extension
c. additional number assigned to a user
if it’s b) or c) you could try changing its type to “Fax only” as opposed to “Voice and Fax”. To test if that gets rid of the voicemail.
The most important thing is that whatever testing you do, write down everything that happens - something like this:
Fax1
From: 012345 12345
To: 034567 55555
Date: April-18
Time: 14:24
What happened: Fax received, silent voicemail (25sec) also received. Two email notifications received - 1 for fax and 1 for voicemail.
Fax2
From:
To:
Date:
Time:
What happened:
and so on. Then raise it to RC support.
To answer your question in the original post:
Am I missing something?
No, there isn’t a setting about generating a voicemail when receiving a fax. Should not be happening imo.
