PRINCIPLES OF ARS MECHANISMS
OVERVIEW
ARS is a mechanism which, during the routing of a call:
- forces the use of the most appropriate path according to the number dialed.
- chooses another path if the most appropriate one is overloaded.
This mechanism is applied independently of the type of:
- trunk group: public or private
- handling: analog or digital
- call: voice or data
ARS is completely transparent for the user; the number dialed is, if necessary, modified automatically
according to the chosen itinerary.
The ARS mechanism can be applied for the following calls:
- outgoing call with manual dialing:
• without specific line seizure
• with specific public line seizure
- using resource keys assigned to a trunk group
- outgoing call with automatic dialing:
• call keys
• personal and collective speed dial numbers, call by name
• last number redial, temporary memory number
- last callers directory
- all types of forwarding and routing to an external destination
- VPN configurations (Transgroupe/heterogeneous network) for converting a public number into a
private number (incoming call) or vice versa (outgoing call).
