[asterisk-bugs] [JIRA] (ASTERISK-23160) Faulty fax detection

[David Cunningham (JIRA)]

    [ https://issues.asterisk.org/jira/browse/ASTERISK-23160?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=215159#comment-215159 ] 

David Cunningham commented on ASTERISK-23160:
---------------------------------------------

Here is the audio. It's 16Mb so not attached to this report:
64.124.219.166/local/200600103-0-1465022714.pcap.gz

The Asterisk trace is only an extract of the channel in question, as the full log is quite a large file (busy system). In any case, I think it's the audio that's really important for this problem.
Thanks.

> We have an Asterisk system with "faxdetect = yes" in sip.conf and sometimes a call is suddenly redirected to the 'fax' extension even though there's no fax tone in the audio. Eg:
> [Jan 13 12:47:52] VERBOSE[12712] chan_sip.c:   == Redirecting 'SIP/product-local-000065d0' to fax extension due to CNG detection
> We can provide a PCAP with audio and an Asterisk full log if required. Thanks.
