asterisk users - Dec 2020 - faxdetect timeout configuration

Hello,

We see there is addition of a faxdetect_timeout option and fix for
FAXOPT(faxdetect) noted in the Asterisk 13 change log:

https://downloads.asterisk.org/pub/telephony/certified-asterisk/releases/asterisk-certified-13.8-cert2-summary.html

Would anyone be able to tell us how to configure this option for calls
arriving via chan_sip? Is it just a matter of setting the FAXOPT(faxdetect)
variable in the dialplan? What we'd like to do is restrict fax detection to
the first N seconds of a call.

Thanks very much for any advice,

A 30,000 ft peek suggests you're out of luck unless you switch to pjsip:
