Notice that the example applies the translation profile in the incoming direction. This
causes it to affect calls coming in from the PSTN rather than outgoing calls. The transla-
tion profile is now in effect, accomplishing the objective of the scenario.
Note: You can do far more with translation profiles (and far more complex patterns that
you can match with translation rules). This is covered more in the CVOICE exam of the
CCNP Voice certification track.
Tip: If you are interested, I (Jeremy) recorded a free video that explains translation rules
in depth. You can watch this video at www.cbtnuggets.com/series?id=440.
With all these various methods of digit manipulation, two questions quickly arise: Which
method gets applied first? Will the router remove added prefix digits because of the auto-
matic digit-stripping rule? Figure 6-16 answers these questions by displaying the order of
operations for outgoing POTS dial peers. The order remains the same for VoIP dial peers;
however, most digit-manipulation commands apply only to POTS dial peers.
