Hadn't really given this much thought, but John's response relative to
a different question sort of got me thinking (with some confusion).
I had the "t" option defined on all C7960 extns, including a couple that
were remote Internet nat 7960s.

I had added the t-option some time ago and didn't document why I did that,
but from memory it seems like it was needed for call pickup, parking or
something like that. (Basic * with sip hard phones and x100p's.)

Since the t-option is _almost_ equivalent to canreinvite=no, to reduce the
number of rtp sessions that must pass through * (assuming all non-nat'ed
C7960s), what functionality might I be accidently impacting by removing
the option from 7960 sip extns?
