Usually you do VOIP billing in so called &quot;Units&quot;, Each unit equals 0.01 cent, meaning 1 USD (or whatever currency you are using in multi-currency billing system) equal to 10,000 VOIP units. Therefore, if you want to bill a call at rate of 10 cents per minute then you should set increment 1,000 units and call interval to 60 seconds. If you shorten the interval to say 6 seconds, then you will charge 100 units per 6 seconds, resulting in same billing as per minute, i.e.<div>
