Extension Locking
Availability: All versions.
Extension Locking allows an 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 exten-
sion. When the user returns, they just unlock their extension to return it to normal operation. You’ll
need to program the restrictions in Class of Service 15 and Toll Level 7 separately. See the Class of
Service and Toll Restriction features for more.
Walking Class of Service overrides Extension Locking.

1. Press ICM and dial ##5.
To unlock your extension:
1. Press ICM and dial ##5 + Enter your pin number + HOLD.
Flash
Availability: All versions.
Flash allows an extension user to access certain CO and PBX
features by interrupting trunk loop current. Flash lets an exten-
sion user take full advantage of whatever features the connected
telco or PBX offers. You must set the Flash parameters for com-
patibility with the connected telco or PBX.
Flash for Single Line Extensions
Class of Service allows you to enable or disable hookflash for analog single line extensions and
2-OPX Modules. If enabled, a single line extension can hookflash normally and use any of the asso-
ciated system features. If disabled, hookflash is prevented. This means the analog extension can not
use any features that require a hookflash (such as Hold, Conference, or Transfer). This may be help-
ful for lobby phones and single line Ringdown Extensions that should not have access to system
features. The option is ignored for Voice Mail ports.
In addition, when enabled:
● A single line extension user cannot seize a trunk and hookflash without dialing. If they do, the
system will disconnect the initial trunk call.
● If a single line extension user hookflashes to place their current trunk call on Hold and then
hangs up, the trunk call will immediately recall the extension.
Feature Quick Steps
1. Press FLASH (if applicable) + Dial the code for the desired CO/PBX feature.
At a single line telephone, hookflash and dial #3 to flash a trunk.
When they leave the office, a
user can secure their phone
to prevent unauthorized use.
Extension users can access
certain CO and PBX
features by interrupting
trunk loop current.
