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:

  • Hi Steve,

    Thanks for that. Perhaps the change to res_fax might help us? I’m hoping someone can say whether or not for sure.
