Charging Calls – Rating Formula Method
This method gives you maximum flexibility for call rating. You create a call formula that is then applied to a call.
Let’s consider the example shown on the figure below. “Charge 1.80 per minute with 1 second rounding for the first minute of the call, then charge 1.80 per minute for the next 2 minutes with 1 minute rounding; after the 3rd minute the fixed surcharge of 0.50 will be applied with 25% probability; and for the next 7 minutes a charge of 1.80 will be applied with 1 minute rounding. Once the call duration reaches 10 minutes, in 50% of all cases it will be disconnected with 30 seconds of dispersion.”
Please refer to the Charging calls – rating formula method section of for more details.

1. On the Rate formula wizard panel, click to add a new element to the formula.
