Steven T. Wheeler updated ASTERISK-20242:
-----------------------------------------

    Attachment: FAX_FAILURE_PARTIAL.pcapng

Here is an example of a FAX which I believe was successful, but failed according to Asterisk.  It has both the SIP and T.38 data.  You will see that it had a few issues early on and had to negotiate down to 9600 but after that it looks correct.

> We are often seeing this error 'FAX_FAILURE_PROTOCOL_ERROR' message when sending and receiving faxes.  There are not many details, but I will attach the fax debug and t.38 capture output for one example.  Please let me know if there is any more information you need.
