2.30.1 Call Cost Display
Description
Each SMDR call record includes a “Cost” field, which is a calculated estimate of the cost of the
call. The call cost updates in real-time and displays on the LIP Phone LCD 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 e
stimate 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 use this information to display and output call cost.
VoIP
For VoIP calls, the system uses the call duration, cost/pulse and decimal values to establish the
call cost estimate. The cost is updated periodically according to the “Elapsed Call Timer”.
Operation
System
Call cost is estimated automatically and output to LIP Phone displays and the SMDR TCP port
