font-family:Arial'>I’m having a bit of trouble with the fax detection
part, my first couple of tries were based on code I saw in the NvFaxDetect
application but the detection method in there doesn’t seem to work with
1.4.18 or my T.38 setup. Specifically the if statement that checks for a
frametype of AST_FRAME_DTMF and a subclass of ‘f’ never evaluates
to true so it continues on to detect my fax tones as voice.<o:p></o:p></span></font></p>

<p class=MsoNormal><font face=Arial size=2><span style='font-size:10.0pt;
font-family:Arial'>My PSTN gateway supports T.38 and sends a re-invite when it
sees a fax, is there a clean method of accessing the t38properties structure
that’s defined in chan_sip from an application? I think if I just check
the t38state for T38_PEER_REINVITE or T38_ENABLED that will be sufficient for
what I need to do. I don’t actually have to do anything with the fax, the
goal is to just check to make sure some of my efax servers are operational. If
checking the state is not the correct way is there another method of detecting
a change to T.38 on the channel from within an app?<o:p></o:p></span></font></p>
