             Summary: Allow arbitrary time for fax detection to end on a channel
                 Key: ASTERISK-26214
                 URL: https://issues.asterisk.org/jira/browse/ASTERISK-26214
             Project: Asterisk
          Issue Type: Bug
      Security Level: None
          Components: Channels/chan_dahdi/NewFeature, Channels/chan_pjsip, Resources/res_fax
    Affects Versions: 13.9.1
            Reporter: Richard Mudgett


Alice dials 5551234 (Bob) through some arbitrary public network
Alice and Bob converse.
After an arbitrary period of time, anywhere from 20 seconds to 7 minutes, Bob hears a fax tone.
Asterisk starts processing the call as though it were a fax.
Alice and Bob are no longer speaking. :(

We need a way to allow fax detection to happen for an arbitrary period of time only, and to be disabled after that time.  Bob understands that he'll lose the ability to handle a mid-call fax if he enables such an option.

* The FAXOPT(faxdetect) option already has a timeout feature but it is broken.  If you try to use the timeout it immediately times out and disables fax detection.  {{FAXOPT(faxdetect)=yes|cng|t38,<timeout>}}
* The channel driver specific fax detect options do not have a timeout feature.
