If i recall it correctly, a non-answered SETUP takes 8 seconds to cause
a reaction at the remote end. Then you should at least 10..12 seconds after
the initial call to the remote receive something. If not, something is
wrong, wherever it is.

If this is really a fix for your problem and does not overlay a bug in i4b
(or your PBX or so) then it seems to be something which can be added.
But i'm still not convinced it is good to add it, would you please send me
an isdntrace output for a failure ?
