When calls are placed to the attendant group or become attendant group calls for the reasons listed below, a check is made for an assigned attendant VDN. If an attendant VDN is assigned and either the system is not in night service or the system is in night service and a night console is available, the call is redirected to the VDN for subsequent vector processing. Otherwise, the call is treated with typical attendant group procedures.
The following occurrences can cause a call to become an attendant group call:
Listed Directory Number (LDN)
Attendant group in coverage path
Attendant control of trunk group access
Calls forwarded to attendant group
Controlled Restriction
Dialed attendant access code
DID/Tie/ISDN intercept treatment
DID time-out due to Unanswered DID Call Timer expiration
DID busy treatment
Security Violation Notification (SVN)
Multi frequency signaling with attendant group as terminating destination
CDR buffer full with attendant group as Call Record Handling Option
Trunk incoming destination is attendant group
Trunk group night service destination is attendant group
Hunt group night service destination is attendant group
Automatic Circuit Assurance (ACA) referral
VDN routes to the attendant access code.
Vector override always applies to attendant VDNs.
