Use the Send All Calls and Call Forwarding (SAC/CF) Override feature to override active rerouting. You can also protect groups of users using this feature. It overrides these active rerouting settings:
Send All Calls (SAC): Redirects all calls to any administered extension.
Call Forwarding (CF) all: Forwards all calls to any adminstered extenstion, off-network or attendant group.
Enhanced Call Forwarding (ECF) unconditional: Forward incoming calls to different destinations depending on whether they are from internal or external sources.
The Overriding of SAC and CF feature is a standard feature starting with Communication Manager Release 5.2.
From Communication Manager Release 5.1 onwards, you can activate the Team Button feature to use its speed dial function and to override a rerouting caused by active SAC, CF, and ECF. For more information, see Team Button.
