The insertion of "}i" into the data stream stems from problems with certain
older time division multiplexed T1 telephone trunks. The  problem is almost
always in a trunk that goes from your prefix to another in your local dialing
area. Newer trunks (at least those multiplexed using newer AT&T DS1 muxes)
don't exhibit the problem. The fix for the problem is to possibly get another
prefix for the troubled line. This will almost always get you a different mux.
However if the problem is in a trunk running from a local central office to
a switching hub (where the toll switch is located, e.g. Berkeley to SF) then
the only fix is to persuade the local phone company to change out the old muxes
on each end... or live with the problem. So far, I'm living with it.
