Cannot send faxes with version 2.2.1 and FritzBox 7490

[firewiremb]

The attempt to send a fax via an analog connection is canceled with the error Phase E handler (0x12) Invalid response after sending a page

I tested the sending with three different fax receivers. The result was the same for everyone.

FRITZ!OS 07.21 / T.38 enabled OS: Linux Mint 20.1 x86_64 (based on Ubuntu 20.04) Roger Router 2.2.1 (flathub version)

The error message is send from the remote fax machine. You can try to alter your settings in Roger Router and play with ECM and service, but at the end fax through IP is always not 100% reliable.

[firewiremb]

Many thanks for your response! I've already tried it with several fax machines. So that I can rule out problems on the recipient side. I've also tried all possible options. With ECM, without ECM, etc. I always get an error message from the recipient side. I've read that a reduced bit rate might help. Is there a possibility in Roger Router to reduce this from 14400 to 9600? Maybe via a config file or something similar?

[janbrummer]

Actually there is, but the speed is auto negotiated between those partners. Anyway, you can give it a try. the hidden setting is called fax-bitrate in gsettings. A lower value for lower speeds.

[firewiremb]

Thank you again for your answer. Unfortunately, I cannot find the gsettings file. In which directory is it stored?

[janbrummer]

They are in ~/.var/app/org.tabos.roger/config/glib-2.0/settings/keyfile

[firewiremb]

Thank you for the information! Unfortunately, the changed bit rate does not eliminate the problem.

However, I have new information on the problem. As I wrote above, I tried faxing with several fax machines. The behavior was the same for all receiving devices. In the meantime, the owner of one of the fax machines contacted me and asked me why I had sent him numerous test faxes.

Further tests have shown that the fax page reaches the recipient reliably, but that the Roger Router nevertheless reports "Fax transmission failed".

When the ECM is switched off, the debug log contains capi_fax_phase_handler_e (): Phase E handler (0x12) Invalid response after sending a page

and with activated ECM capi_fax_phase_handler_e (): Phase E handler (0x10) Invalid ECM response received from receiver

Is it possible that the response from the receiving fax machine to the Roger Router is merely incorrectly evaluated by the Roger Router?

My configuration is such that the Fritzbox 7490 hangs on an analog telephone connection over which the fax is sent. So I don't use VoIP.

Is there anyone who has the same problem with an identical configuration? Or is there someone who can send and receive over an analog phone line without any problems?

[janbrummer]

Are analog still a thing, i thought everything has moved to the digital world. But regarding your problem i'm afraid i can't help here. The actual work is done through spandsp, so those problems must be reported there.

[janbrummer]

Closing as not Roger Router.
