It's been a while since I worked on a cisco voice platform, but unless
things have changed in the past few years I think the only way your
going to get a delay is to use a TCL script.

Before I sent off this message and show how out of the cisco voice game
I am I did some googling to see if there was a better answer and found:

Not sure exactly which part of the cisco config does the magic but its
in there somewhere.
