Nortel 1000 Features And Services Fundamentals page 171

If an Internal CFW call is rejected, a display message is given if the
telephone is digital and has a digit display module (this display message
is the same as that given to a failed CFW All Calls activation request).
Otherwise, overflow tone is given.
Internal CFW is not maintained through a SYSLOAD.
Internal CFW is not supported on Basic Rate Interface (BRI) telephones.
Feature interactions
Attendant Administration
This feature does not support Internal CFW.
Attendant Blocking of Directory Number
The Attendant Blocking of DN feature will override Internal CFW. If the
dialed DN of the set is idle, the DN can be blocked; if the DN is busy, busy
tone is heard.
Attendant Busy Verify
When the attendant is using this feature to call a telephone that is Internal
CFW active, the call will not receive Internal CFW treatment.
Attendant-Extended Calls
When the attendant extends a call on its SRC key to a telephone that is
Internal CFW active, the call on the SRC key will only receive Internal CFW
treatment if it is an internal call.
Attendant Night Service
When a call to the attendant is redirected to the Attendant Night DN that
is defined on an Internal CFW active telephone, the call will only receive
Internal CFW treatment if it is an internal call.
Attendant Overflow
If Attendant Overflow redirects an internal call to a telephone that is Internal
CFW active, the call will remain in the attendant queue, and will not receive
Internal CFW treatment.
Call Forward All Calls
Call Forward Reminder Tone
If Call Forward Reminder Tone Allowed (CFRA) is in effect, whenever an
analog (500/2500 type) telephone with Internal CFW active goes off hook
to originate a call, the telephone sounds the reminder tone. The reminder
tone is either Call Forward Dial Tone (CFDT) or Call Forward/Message
Waiting Dial Tone (CFMW).
