[asterisk-ss7] Two F Links from EWSD to two different asterisk boxes

I  am not sure about the difference of what Bipin sent, except for the order
and apparent removal of directives.  I tried changing the order of the
directives in chan_dahdi.conf, but it had no effect.  It still flaps and
says SLC (0)

Any other ideas?

thanks!
