Alistair,

I had come across this one also a few months back and could not figure
it out until (iirc) tzanger on #asterisk-dev pointed me to
SetCallerPres(allowed). So it seems this is intended behavior. I can't
say I like this rather non-obvious concept so I would welcome a bug with
the request that the presentation bit be preserved.
