It works fine with normal voice calls (two way audio). As for those extra fax-related variables, I just used the [faxin] from the default sip.conf, with no modifications. As you can see from my original email, all I have is [testfax] ;extension 300 for FAX exten => 300, 1, Goto(faxin,s,1)
Anyway, I will tweak the default [faxin] a bit per your suggestions and see. Thanks!
