Extension handset mic not working

Sangoma Hardware Phones
1

I have an extension whose handset mic is not working. I have swapped handsets, swapped handset cords, swapped entire phone, deleted the extension and recreated, manually deleted the extension configuration files. It is not a hardware issue. Somewhere there is apparently a config file that I am not finding that has muted the mic. I have set up dozens of FreePBX systems and hundreds of extensions and never had a weird issue like this. Anyone else?

Details: FreePBX 16, Multiple Sangoma S705 phones. All phones set up on another extension work perfectly. For what it’s worth, the extension is 314.

Is it muted, or is it one-way audio? Is the extension remote? What is physically different to the other endpoints?

Have you created the extension and registered a basic non-Sangoma device to see if that works ok?

What happens if you apply CFW to a mobile for that extension, does it work ok?

Are you using Endpoint Manager to configure the S705? I know you can control the volume of the handset in the template. I remember having to change the default, because it was really quiet, so I increased the db level and that made the handset useful on the s705s.

Had a similar issue once with a Sangoma handset, and it turned out not to be the mic itself but either the cable or provisioning profile. I’d start by swapping the handset and cord with a known working one. If that doesn’t fix it, checking firmware and re-provisioning the extension usually helps narrow it down.
