More research is needed on some of these features.  The retest just 
beeps, then when you hang up, it calls back again.  This ringback is 
in 936-336 on switch: Ericcson AXE-10.  When dialed from an SBC 
payphone, it does not go through.  From a COCOT (936-336-2084), 
message: ERROR 11.  I had no idea that ringbacks had these kind of 
features, so play around and see what you find.
