[hylafax-users] Problems with Error "DIS/DTC received 3 times; DCS not recognized"

[Fabio <fabiobottura@xxxxxxxxx>]

Hello Everyone

I see on the offical Handbook, that i shoul'd mail to this Mailing List, when I have a Faxing Error like "DCS sent 3 times without response".

I can reproduce this error if i try to send a fax via the faxfrontend, or with another program to sending faxes.


Here is my Logfile:
