Station Message Detail Recording (SMDR)
● Blank (Column 74)
● PDC (Columns 75-78)
Identifies the user responsible for outgoing calls. The user is identified by the call
accountability login (##PDC) entered at the originating voice terminal. If no call
accountability is entered, the PDC field is blank.
Figure 2-49 and Figure 2-50 summarize the Call Record and Call Record Header formats.
Considerations
SMDR provides detailed call information on incoming and outgoing calls. This information can be
used to facilitate cost allocation, traffic analysis, and detection of unauthorized calls,
Interactions
The following features interact with Station Message Detail Recording.
Account Code Entry: Allows users to have an account code or project number associated with
each call record.
Bridging of System Access Button: When an outside call is answered or originated at a Bridged
Access (BA) button, the SMDR record for this call will report the bridging station’s PDC number
under the STN column and the principal station’s PDC number under the PDC column. If the Call
Accountability feature is used when originating a call at a BA button, the PDC column will contain
the accountable (entered) PDC number in place of the principal’s PDC.
If two bridged stations attempt to originate a call at the same time, and if the call is completed, the
PDC number of the station that dialed the first digit is placed in the SMDR records under the STN
column.
Direct Group Calling (DGC): For an incoming call to a DGC group that is connected to an
announcement and never answered, the PDC of the Delay Announcement machine will be reported
in the “STN” field of the call record. If the call is answered by a station after receiving the
announcement, that station will be listed in the “STN” field.
Forwarding: When a call is successfully forwarded to an outside number, the call record will
contain the forwarding station and forwarded-to station numbers.
When a Remote Access caller activates Forwarding at a System 25 station, the SMDR call record
shows the incoming trunk number in the FAC field, the PDC of the forwarding station in the STN
field, and the barrier code number in the ACCOUNT field.
Modem Pooling: SMDR records do not reflect modem pool resource usage.
