Call detail recording
Issue 5 October 2002 1605555-233-506
For incoming calls to a VDN, the duration of the call is recorded from the
time answer supervision is returned.
— If answer supervision is returned by the vector (via an
announcement, collect, disconnect, or wait with music command),
and the call never goes to another extension, the VDN extension is
recorded as the called number in the CDR record.
— If the call terminates to a hunt group, the VDN, hunt group, or agent
extension is recorded as the called number as per the administration
discussed above.
— If the call terminates to a trunk, CDR generates the following two
records:
■ An incoming record with the incoming TAC as the dialed
number.
■ An outgoing record with the incoming TAC as the calling
number and the digits dialed through the vector step as the
dialed number.
If “member extensions” is administered on the CDR System Parameters
screen and the call successfully completes to a station via the “route-to”
command, the call record shows an incoming call to that station.
Call Vectoring “route to” commands that are unsuccessful do not generate
ineffective call attempt records.
If a vector interacts with an extension or group that has Call Forwarding
All Calls active, normal Call Forwarding/CDR interactions apply.
Some calls may originally look like intraswitch calls, but result in trunk
calls (for example, a call from a station administered for intraswitch CDR
to a VDN, which ends up an outgoing call on an outgoing trunk). Such calls
will not generate intraswitch CDR records; the CDR record will have a
condition code A - outgoing.
■ Call Waiting Termination
Call duration timing starts when the user answers an incoming call.
■ Centralized Attendant Services
If a CAS attendant extends a call for a user, and CDR is not assigned to the
RLT trunk group, the user’s extension is recorded as the originator of the
call. If the RLT trunk group does have CDR administered, the RLT trunk is
recorded. If a CAS attendant answers a call but does not extend the call, no
CDR records are made.
