Extension Locking allows a keyset extension user to secure their phone when they leave the office. The user may want to do this if their phone has Toll Restriction and Class of Service options enabled that could be easily abused. While locked, the restrictions set up in Class of Service 15 and Toll Level 7 are in force at the extension. When the user returns, they just unlock their extension to return it to normal operation.
[3.01] Corrections have been made to ensure that DND flashes while an extension is locked. This did not always occur in prior version 3 releases.
[3.05] In prior version 3 releases if the user of an extension with Access Level 4 or 5 pressed INTERCOM and dialed the legacy code ##3, and they hadn't stored a PIN code, the extension could lock up. This is corrected and INTERCOM + ##3 sends the user to the Menu + Admin + Erase Pin Number (Menu + 04) menu.
