Thanks to the helpful people on the conference call, I got HylaFAX working today. It turned out I needed to set not only the "fax_enable_t38" variable, but also the "fax_enable_t38_request" variable. Further input showed that the best solution was to change the context in the spandsp.conf.xml from "default" to "hylafax", and make a separate "hylafax" dialplan that has this: <include> <context name="hylafax"> <extension name="FAX" continue="true"> <action application="set" data="fax_enable_t38=true"/> <action application="set" data="fax_enable_t38_request=true"/> <action application="t38_gateway"/> </extension> ...then the normal dialing rules. But as usual, I still have problems. :-( Now I can't get the old analog FAX machine to successfully send FAXes. I have it plugged into a cheap ATA, the OBi<http://www.obihai.com/what-is.html>. It seemed to be working at one time, but that may have been a fluke. On calls through it, I have fax_enable_t38 and fax_enable_t38_request set, and I also set "execute_on_answer=t38_gateway peer" before the call is bridged to the gateway. Should I be using something else? -- Steve
