hi everyone, i am trying to impalement increment billing using Mod_nibblebill as : like for mexico rate is 60/60 means minimum duration is 60 sec and next increment duration is also 60 sec or like for Austria Rate is 60/30 means minimum duration is 60 sec and next increment duration is 30 so if call to mexico duration is 15 sec then it cost for 60 sec and id duration is 61 sec then it cost for 120 sec. but in Austria case if call duration is 15 sec then cost it for 60 sec and if duration is 61 sec then it cost 90 sec so while reading wiki i found that i can use <variable name="nibble_increment" value="30" /> for second problem but want to know how i can set for the 1st case that if call duration is 15 second then call cost for 60 seconds. i read here https://wiki.freeswitch.org/wiki/Mod_nibblebill#Billing_a_Call as Billing of minimums does not exist (yet) so i want to know how that i can implement that or tell me how anyone manage that issue.
