SMDR (Station Message Detail Recording)
2.76.1 Call Cost Display
Description
Each SMDR call record includes a “Cost” field, which is a calculated estimate for the cost of the
call. The call cost updates in real-time and displays in the LCD of iPECS IP and LDP Phones in
place of the call duration.
The cost is determined by:
Fixed charge per “Call Meter Pulse”,
ISDN Advice of Charge or
Estimated cost updated based on Elapsed Call Timer and assigned costing.
The technique selected to determine cost is based on the type of facility (analog CO, ISDN, or
VoIP), services provided by the carrier and the system database.
Analog CO
Where “Call Metering Pulse” service is available from the carrier, the system will apply the
“SMDR Cost per Unit Pulse” and the “SMDR Decimal” to the Call Metering received to estimate
the call cost.
When no “Metering Type” is selected, the system call duration is used with the cost/pulse and
decimal values to estimate the cost of the call. The cost is updated periodically using the
“Elapsed Call Timer” duration.
ISDN
ISDN providers may support “Advice of Charge” information in the ISDN Facility Message. If
assigned, the system will employ this information to display and output the call cost.
VoIP
For VoIP calls, the system employs the call duration, cost/pulse and decimal values to establish
the call cost estimate. The cost is updated periodically at intervals of the “Elapsed Call Timer”.
Operation
System
Call cost is estimated automatically and output to iPECS IP and LDP Phone displays and the
SMDR RS-232 port
Conditions
1. The call cost display begins after the “SMDR Start Timer” expires, if enabled, or at
receipt of the first Call Meter Pulse.
