The Routing Process for a dialled
number that isn’t a DN on the systems is
outlined here. Existing DN’s could be
Extensions, Hunt groups, Phantom
numbers etc.
First the system checks whether an
Access code (AC1 or AC2 ) has been
dialled. If it has, it will firstly remove the
AC code and then restrict its search for
a match to the relevant list.
The subsequent match will also attach a
Call Type to the call which is carried
along with it.
If the first digit dialled is neither of the
two AC codes then the system will
search through the Steering codes
(Distance, Local & Trunk) for a match
again with a call type being added.
The generated match will point to a
Route List Index, (RLI) this is a table
which directs the call to the right Route
off the system. It will also apply a Digit
Manipulation (DMI) before forwarding to
the route and finally the trunk.
The DMI will delete and insert digits as
required .
