<br><tt><font size=2>So, if i understand the question correctly, you have:</font></tt>
<br><tt><font size=2> Asterisk SIP-> SPA3102 FXS
-> Analog fax machine</font></tt>
<br><tt><font size=2>and the PBX to SPA3102 communications are T.38 before
converting to analog to go to the fax machine. Then in the other situation
you would have:</font></tt>
<br><tt><font size=2> Analog line -> SPA3102 FXO
port -> Asterisk SIP</font></tt>
<br><tt><font size=2>and the SPA3102 to Asterisk communication isn't doing
T.38?</font></tt>
<br>
<br><tt><font size=2>If that is the case, the only thing I can think of
is that maybe they were not thinking that many people would want to do
the second situation with a low end device? I imagine the main use case
it to keep the old analog device around after switching to SIP delivery.
Probably didn't expect to see analog delivery that gets translated to a
sip fax endpoint. </font></tt>
<br>
<br><tt><font size=2>Though I do agree that once you have the transcoding
option, I would think it would be trivial to apply it to both ports.</font></tt>
