Hi, I have got a power dialer its getting who will be called or not from MSSQL DB access. If my DurumID column value is 1 then its will get number. Once Loop is complete im updating DurumID to 2 so next loop power dialer can not get last record for re-call. My algorithm is like this. When Loop is completed for testing purpose i'm changing DurumID to 1 for give this record re-call situation but Power Dialer not calling it until i have restart services.. I think variables not resetting before 3cx service restart. Thank you. Schema is attached..
