Charging Calls – Rating Formula Method

This method gives you maximum flexibility in call rating. You create a call formula which is then applied to the 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 call, then charge 1.80 per minute for the next 2 minutes of the call with 1 minute rounding; after the 3rd minute of the call the fixed surcharge of 0.5 will be applied with 25% of probability; and for the next 7 minutes a charge of 1.80 will be applied with 1 minute rounding. When the call duration reaches 10 minutes, it will be disconnected in 50% of all cases with 30 seconds of dispersion.”

 

Please refer to the Call Rating Formula Wizard section of the PortaBilling Web Reference Guide for more details.
