Forced Call Disconnection
What’s this?
Forced Call Disconnection enables extension users to disconnect a busy extension at will, and free the system
resources (access to extension) for themselves.
How it works
Forced Call Disconnection of an Extension:
• A, B and C are extensions.
• A and B are in speech.
• C calls B and finds it busy.
• C uses Forced Call Disconnection by dialing the feature command.
• C gets confirmation tone, while A and B get error tone.
Forced Call Disconnection of a Trunk:
• A and B are extensions. C is the external party.
• A is in speech with C on Trunk 1.
• B grabs Trunk 1 using Selective Port Access, but gets busy tone.
• B uses Forced Call Disconnection by dialing the feature command.
• B gets confirmation tone. A gets disconnected and gets error tone.
• B must grab Trunk 1 again to get the dial tone of the network.
To be able to use Forced Call Disconnection, the extension user must have a higher “Priority” than the
extension user whom he/she tries to forcibly disconnect.
To be able to use Forced Call Disconnection on a busy trunk, the extension user must have grabbed that
trunk using “Selective Port Access”. If the extension user has grabbed the trunk using a Trunk Access
Code, the feature code to dial Forced Call Disconnection will not work.
How to configure
To be able to use Forced Call Disconnection, the extension must have:
• Forced Release feature enabled in the Class of Service. For instructions see “Class of Service (COS)”
and “Station Basic Feature Template”.
• As Forced Call Disconnection on a busy trunk is possible only if the extension user has grabbed that trunk
using Selective Port Access, this feature must be enabled in the Class of Service of the extension. For
instructions see “Class of Service (COS)” and “Station Basic Feature Template”.
• Higher Priority assigned than other extensions. See “Priority” for instructions.
