7.2.4 Check costs for a call

The checkCallCosts function provides all the information you need to calculate costs for a specific call, however it is not necessarily straightforward to work out what types of number are involved in an overlay. The callCostGet function allows you to specify the overlaying and destination numbers in use, and the date of the call. The function then returns the peak, offpeak and weekend pence per minute charge or refund for that call.

Example

Check what it would call to route a geographic number to a freephone yesterday.

• Specify the overlaying number: DNI=01234567890
• Specify the overlaid number: DDI=08008008008
• Specify the date of the call: date=2024-04-25
