5.22.3.8 Planning ARS
Using the methods shown in the previous examples, it is possible to achieve ARS that meets most requirements.
However the key to a good ARS implementation is planning.
A number of questions need to be assessed and answered to match the system's call routing to the customer's dialing.
· What
What numbers will be dialed and what needs to be output by the system. What are the different call tariffs and the
dialing codes.
· Where
Where should calls be routed.
· Who
Which users should be allowed to use the call routes determined by the previous questions.
· When
When should outgoing external calls be allowed. Should barring be applied at any particular times? Does the
routing of calls need to be adjusted for reasons such as time dependant call tariffs.
