Log feature on 2420 - G3V11

[sistech]

It seems since implementing agent id with users utilizing the 2420 set the log feature no longer works when the agent id is dialed. It works when the phone extension is dialed only. However, at our other site that utilizes S8700, log feature works with both agent id & phone extension. Anyone else have this experience. It this a because of our type of switch?

Thanks in advance,
