The three basic options supported for Call forward are:
Call Forward, All Call: Call Forward All Calls (CFW) automatically forwards incoming calls to another destination, within or outside the system. Only calls to the station extension (Prime DN on CS 1000) or any single-appearance secondary number on the telephone are forwarded. Numbers shared with other users cannot be forwarded in this manner. Outgoing calls can still be placed from the telephone when Call Forward is active.
Call Forward, No Answer: Call Forward No Answer automatically forwards unanswered calls to another destination. The customer can specify the number of rings before the system invokes Call Forward No Answer. CS 1000 supports a default of four rings.
Call Forward, Busy User: Call Forward Busy (CFB) automatically routes calls to a target when a telephone is busy.
These options allow the calls to be treated differently based on the call type. This permits calls from internal parties to receive a different treatment than external parties.
An option also exists to allow or deny a user to call forward to an external number.
Note:
The Call Forward Busy and Call Forward No Answer are configured to terminate at the same destination.
