Call Forward and Hunting take precedence over Call Waiting. If Call Waiting
is allowed, Camp-On is not attempted. If Call Waiting is not allowed,
station-to-station Camp-On is automatically attempted. If this succeeds,
Enhanced Override can still follow. If Camp-On fails because there is no
external call, Forced Camp-On and Enhanced Override may still work.
However, if Camp-On fails due to other limitations, Forced Camp-On and
Enhanced Override will also not work.
Even though Camp-On will still function when Warning Tone Denied (WTD)
Class of Service is defined, Forced Camp-On requires Warning Tone
Allowed (WTA) Class of Service.
Camp-On requires an external call on hold. Forced Camp-On can be done
without a call on hold, or with both internal and external calls on hold.
Camp-On Classes of Service (Camp-On From another telephone Allowed
[CPFA], Camp-On From another telephone Denied [CPFD], Camp-On To
another telephone Allowed [CPTA], and Camp-On To another telephone
Denied [CPTD]) apply to Forced Camp-On and automatic Forced Camp-On
(AFCO) only. They do not apply to Station or attendant Camp-On.
If a telephone is denied Forced Camp-On by Class of Service, Enhanced
Override may still be attempted.
