[asterisk-users] spandsp logs?

[Francesco Francesconi]

Hello everybody.
I am trying to build a fax gateway system based on spandsp.
Everything is working fine except that I don't know how to keep track of
the final status of the fax call (if the fax went through ok or failed
somewhere in the transmission).
I've seen in the src directory of spandsp (I'm using the 0.0.2pre26
version) a logging module that (I suppose) gets compiled with spandsp,
but wasn't able to find out how to enable it nor where it saves logs at.
Anybody knows how I can achieve this?
Thanks in advance

Francesco
