Yes, i have fixed it.
1) if you change the number combination from number choice(add/remove any row) from admin>settings. if at that time if any cron script is in queue server or running mode then you will get notification.once the process finished then next time you will not get any notification.
Notes: currently i can test the cron script duw to server error that is occured after you have changed the server settigs.see more detail in email i have sent you with subject “Server Related Error in Laravel Voip” yesterday.
2) i have fixed this point. you can check it now.
