I think I understand you. Your first dialtone in this case would be provided
by your PBX. Unless the PBX is configured to find you a line and seize it
for you (using anyh of the methods mentioned below by Jay), then you will
need to dial *another* 9 in order to access the VoIP router's dialtone this
time. Normally if the PBX is configured correctly you do not even need that.
Another scenario is when the second dialtone happens to be the one provided
by the *far end*, in which case direct-inward-dial on the far end router
would eliminate this dialtone for you and dials the extention. The same
thing can be configured on the PBX as well.
Bottom line, if you want to emulate 2 dialtones then they would normally
come from 2 different sources (routers/PBXs/COs). Tell us the details and we
may be able to help you.

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?
