[hylafax-users] Fax --> Asterisk --> PSTN --> Asterisk --> Hylafax = High consecutive bad lines

[syscon@xxxxxxxxxxxxx]

I always get many consecutive bad lines in the following setup and fax never gets through:
Fax --> Asterisk --> PSTN --> Asterisk --> Hylafax (never gets through)

The other way around is no problem:
Hylafax --> Asterisk --> PSTN --> Asterisk --> Fax  (OK)

Normally all faxes comes through OK.
Here is a session transmission:

The "Fax" behind Asterisk is not a fast box: running on Mini-ATI VIA C7 processor.
Though it has no problem with receiving faxes and sending or receiving faxes to/from stand alone machines.
