Since the telephone must be on-hook to go into the Admin mode, the Headset On/Off
●
button must be in the OFF position.
A telephone that is in the Admin mode of TSA cannot be remotely unmerged by the PSA
●
feature.
If a user has Abbreviated and Delayed Ringing active, a call can be silently ringing at a
telephone and the user may not realize it. This ringing prevents the user from entering the
Admin mode of TSA.
