Feature Reference
Call detail recording
Intraswitch CDR transfer records are output when both the calling number (originator) and dialed
number (terminator) drop from the call. The duration of the call is from the time the terminator
answers until both the originator and terminator have dropped from the call.
If ITCS is enabled and an incoming trunk call is transferred to a local extension that is optioned
for Intraswitch CDR, the call produces an incoming trunk call record. It does not produce an
Intraswitch record.
Users cannot dial an account code when transferring a call to another extension, unless they have
console permissions. However, a user transferring a call to a trunk can dial an account code before
dialing the ARS or TAC.

Trunk-to-Trunk Transfer
Although they are not really conference calls, Trunk-to-Trunk Transfer connections are treated as
such for CDR purposes. A separate CDR record is generated for each trunk in the connection.
Unanswered Trunk Calls may or may not be recorded depending on administration. You can
administer each trunk group so that unanswered calls are recorded if they remain unanswered for
a specified period of time.
If Incoming Trunk Call Splitting is active, a trunk-to-trunk transfer produces a record of the
incoming call, and a record of the outgoing call. The outgoing call record shows the duration from
the time the call was transferred until both parties drop. The incoming call record shows the
duration from the time the station receives the incoming trunk call until both parties drop.
•
Uniform Dial Plan (UDP)
If one user calls another user via a UDP extension number, and the trunk group used has CDR
assigned, CDR records the following information:
— Condition Code — 7
— Access Code Dialed — blank
— Access Code Used — trunk access code of trunk used
— Dialed Digits — Uniform Dial Plan extension
•
VDN Return Destination
An incoming call does not generate a CDR record until the originator drops from the call. CDR
creates a record when a call goes to the return destination VDN, the originator has not dropped,
and vector processing — that is, the return destination VDN — routes the call to an outgoing
trunk. CDR does not create a record if vector processing routes a call from the return destination
VDN to an internal call. The call record shows only the first VDN that the caller accessed, no
matter how many other extensions are involved in the call.
If an incoming VDN call is routed to a station, CDR includes the station in the record. If an
incoming VDN call is routed to an outgoing trunk, CDR includes the VDN in the record.
