Hi Dale,

The following is our calls_insert trigger.

CREATE TRIGGER calls_insert ON Calls FOR INSERT AS DECLARE @rows INT UPDATE RadIPAddresses SET State = CASE WHEN i.AcctStatusType IN (1,3) THEN 2 WHEN i.AcctStatusType = 2 THEN 0 ELSE State END FROM RadIPAddresses ri, inserted i
 WHERE ri.NASPort = i.NASPort
 AND ri.NASIdentifier = i.NASIdentifier UPDATE RadConcurrency SET Connections = Connections + CASE WHEN i.AcctStatusType IN (1,3) THEN 1 WHEN i.AcctStatusType = 2 THEN -1 ELSE 0 END FROM MasterAccounts ma, SubAccounts sa, RadConcurrency rc, inserted i
 WHERE i.AccountID = sa.AccountID
 AND ma.CustomerID = sa.CustomerID
 AND rc.GroupID = ma.GroupID
 AND (rc.AccountTypeID IS NULL OR rc.AccountTypeID = sa.AccountTypeID) SELECT @rows = 0 SELECT @rows = @rows + 1 FROM inserted GROUP BY NASIdentifier, NASPort, ServerID UPDATE ServerPorts
        Set Username = i.Username,
  AccountID = i.AccountID,
                AcctStatusType = CASE WHEN i.AcctStatusType in (1,3) THEN 1 ELSE i.AcctStatusType END,
  CallDate = i.CallDate,
  FramedAddress = i.FramedAddress,
  CallerID = i.CallerID,
  ConnectInfo = i.ConnectInfo,
  AcctSessionID = i.AcctSessionID
        FROM ServerPorts sp, inserted i
        WHERE sp.NASIdentifier = i.NASIdentifier
 AND sp.Port = i.NASPort
 AND (i.CallDate >= sp.CallDate OR sp.CallDate IS NULL) IF (@@rowcount <> @rows)
 /* SNMPUser should add the port for all except 10 (ascend) */
 INSERT INTO ServerPorts
 SELECT i.ServerID,i.NASPort,i.NASIdentifier,NULL,0,0,MIN(i.Username),MIN(i.AccountI D),MIN(i.AcctSessionID),CASE WHEN MAX(i.AcctStatusType) in (1,3) THEN 1 ELSE MAX(i.AcctStatusType) END,
 Case when MIN(st.SNMPType)=1 then MIN(st.SNMPUser) else MIN(st.SNMPUser) + convert(varchar(9), i.NASPort) END
 FROM inserted i, Servers s, ServerTypes st
  WHERE s.ServerType = st.ServerType
  AND s.ServerID = COALESCE(i.ServerID,(SELECT MAX(s.ServerID) FROM Servers s, inserted ii WHERE s.IPAddress = ii.NASIdentifier))
  AND NOT EXISTS (SELECT * FROM ServerPorts sp, inserted ii WHERE sp.NASIdentifier = ii.NASIdentifier AND sp.Port = ii.NASPort)
 GROUP BY i.NASIdentifier, i.NASPort, i.ServerID
 END UPDATE SubAccounts Set TimeLeft = sa.TimeLeft - (i.AcctSessionTime/60 + 1) FROM SubAccounts sa, inserted i WHERE ((i.AccountID IS NULL AND sa.Login = i.Username) OR (i.AccountID IS NOT NULL AND sa.AccountID = i.AccountID))
 and sa.TimeLeft IS NOT NULL
 and i.AcctStatusType = 2

Could you kindly let us know what changes we need to do.
