Automatic routing — general
Avaya Communication Manager automatically routes outgoing calls using the most preferred (normally
the least expensive) route available at the time the call is placed. Generally, AAR routes calls over a
private network and ARS routes calls using the public network numbering plan. However, both AAR and
ARS support public and private networks.
