Hi Jared, the behaviour of rxfax changed between 1.2rc3 and trunk.  In
1.2rc3 rxfax doesn't issue a reinvite if it detects fax, in trunk it does.
I disabled this feature in rxfax for a client who needed to receive in *LAW
due to a non-interoperable t.38 gateway.

maybe because it can't traverse the previous directories.
Try to specify a path like /tmp/test.tif to see if it works.

depends on the codec you're using.

Well I was able to get it working I had an extra ( in my sipfax context.
exten => fax,n,RxFAX((${FAXFILE}|debug|ecm) 
should be exten => fax,n,RxFAX(${FAXFILE}|debug|ecm)

However with the codec being ulaw I still have to initiate the 

SipT38SwitchOver() command to get it to work as t38.

I did also notice if during a fax comes in and I have verified its using t38
by checking for activity with udptl debug ip I see that the codec shows ulaw
when I do sip show channels. 

Is this normal?

I haven't tested sending faxes yet. I will do that soon. Then I'll work on
pass through support.

Jared
