Considerations
• With CPC-A and CPC-B Versions prior to 2.0, calls cannot be forwarded
to an extension that already has call forwarding activated. In other words,
phone “A” can only forward to phone “B” if phone “B” is not forwarded.
Beginning with CPC-B Version 2.0, calls can be forwarded to extensions
that have call forwarding activated. For example, phone “A” can be
forwarded to phone “B,” even if phone “B” is forwarded to voice mail.
• In CPC-A and CPC-B Versions prior to 5.0, DND and Absence Messages
cancel Call Forwarding.
Beginning with Version 5.0, calls to an extension with DND or Absence
Message turned on are treated differently, depending on whether they are
trunk or intercom calls: Intercom calls receive busy tone; trunk calls are
routed to the extension defined in permanent call forwarding.
The following types of incoming trunk calls follow permanent call forward
settings:
- Direct trunk calls (including DID/DNIS)
- Transferred trunk calls.
