[Asterisk-Users] RxFAX generates no tiff file

[Mike Heininger]

Hi,

I am trying to receive a fax with the spandsp library.
The sending fax says "success" but there is no tiff file generated.

I use "exten => 7000,1,rxfax(/tmp/testfax.tif)" in my extensions.conf.
The connection is via SIP/G.711 as I have read on the list that this 
can sometimes work (I know Fax over IP is troublesome without T.38).

I think the transmission should not be the problem because of the 
"success" on the sending fax.

This is the debug output.

Am I missing something?

TIA,
Mike
