The Sippy Softswitch can round the Call Duration to the nearest second in two ways. This feature is part of version 4.1 Sippy Softswicth.


Round (Default method)

This method rounds the call duration to the nearest second based on the typical round approach. For example; 

A call with a duration of 1 second 400 milliseconds will be rounded down to the nearest whole second. The call duration will be recorded as 1 second.

A call with a duration of 1 second 500 milliseconds will be rounded up to the nearest whole second. The call duration will be recorded as 2 seconds.


Round Up

This method rounds the call duration up the the nearest whole second. For example;

A call with a duration of 1 second 100 milliseconds will be recorded as 2 seconds.

A call with a duration of 1 second 500 milliseconds will be recorded as 2 seconds.

A call with a duration of 1 second 0 milliseconds will be recorded as 1 second.


The following table illustrates the results of both rounding methods

Seconds Default Rounding RoundUp
60.0 60 60
60.1 60 61
60.4 60 61
60.5 61 61
60.9 61 61
