Fax images compressed

[RivellSupport]

Hello,

This is the first time we have used the 3CX fax server for a client. We are having an issue with the inbound fax images being compressed and unreadable. It happens maybe a few a day and it's at random. I ruled out a bad fax machine on the other end, or a particular sender. Any ideas on settings to adjust?

System information:
Hosted 3CX - AWS - Windows Server

Inbound DID set to "Send Fax To" extension e-mail

Any input would be greatly appreciated.

What version of 3CX? Are you using T.38 or g.711 fall back? Are you using a supported provider?

 

[RivellSupport]

Version: 6.0.655

SIP: Flowroute (T.38 supported)

I'm using the built in 3CX fax server to convert inbound faxes to email with G.711 to T.38 fallback enabled.

 

[cobaltit]

So I'd first disable G.711 fallback so ensure you are only using T.38.

I'll give that a shot and report back. Thanks for the suggestion.

@cobaltit That has worked out so far. Thanks for the suggestion!

Great. T.38 doing it's job, I like it!

Thanks for updating the thread.
