In my original post I had stated I created the CHAN_PJSIP for the SPA112 which connects. Then I modified the incoming route options to detect faxes and send them to that extension. And I modified the Asterisk SIP settings for chan sip to add faxdetect as well. The DETECTION is working. The EXTENSION is not being used as a fax extension as the errors states. Any documentation I see on this says to click the check box on the extension to indicate it is a fax however that option does not exist.
