■ Hunt Groups and Automatic Call Distribution (ACD) Splits
The phone’s extension and COR is used to determine ANI for a hunt group
or ACD split.
■ Multimedia Call Handling (MMCH)
For call origination, multimedia complexes use the COR assigned to their
phones.
■ Personal Station Access (PSA)
For ANI, the PSA extension and COR overrides the phone’s extension and
COR.
■ Remote Access
A remote access barrier code COR is not used for ANI. The extension’s
ANI is used if an extension originates the call, and the ANI for the switch is
used if the originating endpoint is an incoming trunk.

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