Thanks Kevin,
We managed to get the ReceiveFAX going, while making some minor changes
to the code, like, for example, using the ${UNIQUEID} for the file name.

Thank you Kevin,
We'll upgrade our server to 1.6.2.12 and try again.
Another question: Is there (expect for the admin guide that we didn't
succeed to understand the example in) an example somewhere for

Hello,
I'm trying to send a tif file, using Fax for Asterisk and the call is
executed, but when I get the reINVITE with T.38 data, the local server
doesn't recognize that we have this capability and sends a 488 message.
These are the logs:
--- SIP read from UDP:xxx.xxx.xxx.xx8:5060 ---

You don't say anything about what you're trying to send / receive against.
Here's how you should troubleshoot:
* start with a 'real fax machine'
We don't have an ATA and fax machine.
The whole point (as I specified in the header and initial message) is the
attempt to use Fax for Asterisk to send the message.
As I showed in the logs, the remote carrier sends a proper T.38 reINVITE,
but our Asterisk doesn't accept, despite the fact that
From what I have read over the last few months, you should invest in Motrin
before trying T.38 faxing with or without FFA - it can (possibly) be done,
but it has beaten some folks into the ground trying it.
Could be a codec issue.

Digium claims that their FFA is the best and most compatible solution and
they give one channel for free, but do not provide support for those that do
not buy more channels, but why buy more channels if the free/test one
doesn't work?

Fair enough Kevin :-) It's just that your documentation for this product is
so limited that without extensive search online and the assistance of
others, it would have been impossible for us to make any progress and we
haven't reached the ReceiveFax part yet ;)
