You're comparing apples to oranges. Direct inward dial is an application
where a PBX receives digits from an outside trunk to steer a call to a
given destination. In its pure form, it's wink start with battery reversal
for supervision and generally uses the wink for "ready to accept digits"
as opposed to sending dialtone. It's a trunk-side application, and also
in its pure form is inbound only.
Dial 9 for outside is a line-side application. The "9" is a trunk code
that the PBX uses to connect to an outside line. The dialtone may change
if the PBX provides you with the trunk's dialtone as opposed to simply
providing its own. Some switches will supply their own dialtone to the
user, particularly if using a wink-start trunk on the outbound side or
if a decision needs to be made for call routing after the initial "9".
Specifically what is the scenario that you're trying to configure? In
other words, what's the problem you're trying to solve?
