All inbound faxes fail with an invalid fax size error, although outbound faxes can be sent without any transmission error.
- GFI FaxMaker
- Bintec RT1202
Please verify whether the firmware of the Bintec router is up-to-date. If yes, please verify whether the correct device profile has been selected for the attached fax device under Lines / Devices
> ISDN type
. If not, please select the correct device profile and restart both GFI FaxMaker services.
A wrong device profile was configured for the attached fax device in GFI FaxMaker configuration, hence inbound faxes were not properly handled.
