asterisk users - Jan 2008 - txfax_exec: Transmission loop error

Hi,

I just installed Antonio Gallo's agx-ast-addons package
in order to use app_txfax with asterisk-1.4.

Compiling according to docs went well.
However, I'm getting an error after the first page
of fax:

/usr/src/agx-ast-addons/app_txfax.c:438 txfax_exec:
    Transmission loop error

The (very first) page is transferred perfect anyway.
Then app_txfax unfortunetly stops the transmission.

Any hints?


Regards,
Roger.
