Billing Increment and Related¶
On the picture above you may see how billed call duration is calculated basing on real duration, billing increment, min and free parameters. On the picture above, increment=6, min=30, free=12.
Thus, call with duration of 35 seconds will be billed as call with duration of 30, and call with duration of 50 seconds will be billed as call with duration 42 seconds.
