Just thought I'd run this by you.
We've been running connected to our Definity G3si R6
via TN767 <--> TE410P and have had no problems.

Our zapata.conf settings our just
a little different, might give you something
to try. We had some strange problems when set as you have
above.

switchtype = 5ess
overlapdial = no
signaling = pri_net
