call generator on asterisk

first we will have global configuration switch ip call rate concurrent calls list of recordings to play during calls then we will create a new task i will add numbers to it like this number , number ofcalls, duration of each call in seconds, interval in minutes if calls more than one like this 167#2001111992244,1,1320, to call this number only 1 time with duration of 1320 seconds or 165#2101111992244,10,50,30 to call this number 10 times each time is 50 seconds at 30 mins interval we need to set duration random which should be within 10% above or below defined number so for the first task the call should be from 1188 to 1452 seconds so you can put this call duration any number between that range so when i upload like 100 numbers with duration 1320 seconds you should translate to random duration within this range i can add to the current task or stop the current task and start new one we will have 3 tables one with active call number, current duration , the duration the call should disconnect at forr example 1067#2001111992244 20:53 22:12 another table for pending tasks number , duration of the call , time at which this pending task should be run 065#201111992244 22:12 wednesday 31st 17:53:50 and 3rd table for finished tasks number, successful calls, failed calls , total duration , pending , active 167#2001111992244 1 0 22:12 0 0 meaning this number has 1 successful call and 0 failed and duration was 22minutes and 12 seconds and has no pending tasks or active tasks table of finish tasks shouldnt have any repeated numbers as you can see you can add success or fail and total duration to each number counter these tables should be cleared when i stop the task or run a new task but not cleared incase i add task to the current task each number in the list has the following format 000#(prefix so it knows to which gateway it should go ) 4 digits 00( ctrl number to call from this gateway ) 2 digits 000000000( number to call ) so in this case 167#2001111992244 167# 20 01111992244 so you cant call at the same time same prefix with the same ctrl so if you are sending calls you can call these 2 numbers at the same time 167#2001111992244 167#2001093998318 as both 01111992244 01093998318 will be called from same gateway and same ctrl at same time and thats not possible another thing you can call same destination number at the same time 167#2001111992244 065#2501111992244 these calls are from different gateways and different ctrl but calling the same number and thats not possible so i will have task status which is telling do we have running task or not if we have running task we can add to it or we can end it if we end current task all tables will be cleared we can export tables before we end the task or while task is running if we add to task to already running task and i add this 065#201111992244 and you already have either active or pending for it you should ignore this from adding if i added these 2 tasks 065#2001111992244,1,900, 167#1501093998318,10,50,20 you will create the following tasks 065#2001111992244 to be called once for duration within the range between 10%below or above 900 seconds lets say 951 seconds 10 tasks at 10 mins for interval for 167#1501093998318 each for a duration within 10%below or above 50 seconds like 167#1501093998318 52 seconds august 31st 2017 9:14:51 167#1501093998318 55 seconds august 31st 2017 9:24:51 167#1501093998318 48 seconds august 31st 2017 9:34:51 and so on these tasks should be seen in the pending list if any failure of any call occurred the call should be retried failure means the call didnt complete the duration you set for it if we stopped current task all tables got cleared and all active calls should hang up
