What is increment

Increment is amount of time in which the call will be billed. It is counted in seconds.

Example:

• Imagine call length is 15s
• Rate for 1 min is 1 EUR/min (for simplicity reasons)

Then:

• If increment is 1, then call length will be counted as 15s and call price will be 0.25 EUR (1/60*15) - increment is 1, so call can be 1, 2, 3... in length. 15s is exact length of call.
• If increment is 10, then call length will be counted as 20s and call price will be 0.333.. EUR (1/60*20) - increment is 10, so call can be 10, 20, 30... in length. 20s is nearest to 15.
• If increment is 20, then call length will be counted as 20s and call price will be 0.333.. EUR (1/60*20) - increment is 20, so call can be 20, 40, 60... in length. 20s is nearest to 15.
