Hello to everyone! This is my firs post!

I have this problem under a Cisco CallManager 5.1.2.1000-11 with Attendant Console 5.1(1):

When I want to transfer a call, sometimes the previous number entered appears in the "Enter Number" field.

The problem is that, even if I delete the number and I enter a new one, it appears again at the beginning of the entered number, so I have to delete the first digits and then press quickly the Enter key to begin the transfer (sometimes I'm not so quick, so the previous number appears again, with the result that the dialed is obviously wrong).

This abnormal behavior implies an obvious waste of time (and patience...).

Is there a way to remove this autocomplete feature or, at least, to avoid the abnormal behavior described above?

Thanks in advance for your help!
