Description:Using SendFAX as an answering machine (argument "a") the transmission of a fax failed after the first page of three (debuglog1.txt).
Starting the fax transmission by calling asterisk and transfering the call to the same faxmachine all three pages are transfered successfully but app_fax end with "Transmission error" (debuglog2.txt). Both fax transmissions were done between asterisk and Fritz!Fax, a CAPI Software fax by AVM.

As you are using chan_capi, this is not something we can support here. Please contact your vendor for support with this issue.

The error of only transmitting the first page of a multipage fax seems to be channel independent and not chan_capi related. I reproduced this error using chan_misdn (debuglog1-misdn.txt). This problem does not occur with all fax-machines.

Starting the fax transmission by calling asterisk and transferring the call to the same fax-machine all three pages are transferred successfully. The "Transmission error" does not occur using chan_misdn (debuglog-misdn2.txt).
