[asterisk-bugs] [JIRA] (ASTERISK-20242) Error sending fax: FAX_FAILURE_PROTOCOL_ERROR

[Steven T. Wheeler (JIRA)]

    [ https://issues.asterisk.org/jira/browse/ASTERISK-20242?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=199450#comment-199450 ] 

Steven T. Wheeler commented on ASTERISK-20242:
----------------------------------------------

I am not sure I will be able to get a capture with the SIP as well.  The problem is I have to leave the packet captures running for days on a production system while waiting for the problem to occur.  But the capture files grow to be several gigabytes and Wireshark is unable to handle files that large.  Breaking the captures into chunks small enough for Wireshark to process causes the call to be distributed across several files.  Is there nothing we can tell from the T.38 alone?

> 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.
