Hello, I am working with 1.8.32.2 which I have patched with t38-gateway and
PRACK. t38 is tested and working fine with Zoiper client but I can't get the
t.38 software from Biscom (FAXCOM) to talk. In my first attempts I found
FAXCOM announces that it supports 100rel so I added the PRACK patch hoping
that would do the trick. Now it gets a little further but * complains about
rejecting a non-primary audio stream.

Could this be a problem with 1.8 not liking the second media stream or is
there some more configuration tweaking to be done?
