---------------------------------------------------------------------- 
bug16790.diff.txt workaround to limit unacknowledged i-frames to 3 instead
of the default of 7.

I'm sure other equipment other than our Jtec do not like 7 outstanding
I-frames.

This turns out to be real easy to fault, ring in through the ISDN 3-4
times quickly, and abort the each call.

If pritimer=>k,3 in chan_dahdi.conf wasn't overwritten by libpri, then
this patch isn't needed. But thats in
