ARS Calls Go to System Operator (Unassigned Extension)

For an incoming call, if the PassageWay Telephony Services
application uses the length of ANI information to differentiate
PSTN calls from UDP calls, a PassageWay Telephony Services
client displays a non-local dial plan call as an inside call.
For an incoming call, if the PassageWay Telephony Services
application uses the presence of a trunk identifier in the delivered
event to differentiate PSTN calls from UDP calls, a PassageWay
Telephony Services client displays a non-local dial plan call in the
same way it does a PSTN call.
For an incoming PSTN call that enters the private network on a
PRI trunk with an ANI of length shorter than seven digits and
crosses PRI tandem trunks only, the recipient PassageWay
Telephony Services client display depends on the PassageWay
Telephony Services application implementation.
If none of these factors explain the problem, contact the application provider. If
the application provider instructs you to do so, call the Lucent Technologies
Helpline at 1 800 628-2888; consultation charges may apply.
ARS Calls Go to System
Operator (Unassigned Extension)
Possible Cause: System managers in your private network may have set up
ARS and remote access to route outgoing calls to PSTN facilities on switches
where these calls are most economical.
What to Do: If such calls are reaching a system operator (unassigned
extension) on a private networked system, rather than being routed to the
PSTN, the coordinating system manager must check the tandem facilities that
carry calls to the system where the operator is located. The problem is caused
when one or more tandem trunks has no switch identifier (the factory setting).
If this is not the problem, call the Lucent Technologies Helpline at 1 800
628-2888; consultation charges may apply.
