Feature Reference
To use Camp-On, the feature must be activated while the person is listening to
ringing, a busy tone, or call-waiting ringback. Camp-On can not be activated at
other times, and no error tone sounds when a user unsuccessfully tries to use
Camp-On at an inappropriate time.
Camp-On cannot be used on a system that includes a voice messaging system.
Telephone Differences
Direct-Line Consoles
When a Direct-Line Console (DLC) system operator uses Camp-On to transfer a
call to a busy extension, the call is placed in the call-waiting queue and the
caller hears the call-waiting tone whether or not the user has the Call Waiting
feature activated.
If the system is programmed for One-Touch Transfer with automatic completion,
the operator uses Camp-On by pressing the Transfer button, dialing the
extension manually, and activating Camp-On.
If the operator presses an Auto Dial or DSS button, the transfer is automatically
completed and Camp-On cannot be used.
Queued Call Consoles
A Camp-On button cannot be programmed on a QCC. Instead, you release a
call to a busy extension by selecting
return to the QCC queue until the Camp-On return interval expires. If you press
the Release button, the extension being called receives the call-waiting tone
and the call returns to the QCC queue when the transfer return interval expires.
To use Camp-On when the system is programmed for Automatic Extended Call
Completion, you must press the Start button, dial the extension manually,
activate Camp-On, and press Release or hang up. If you press a DSS button,
the transfer is automatically completed and Camp-On cannot be used.
Other Multiline Telephones
Camp-On can be used when a multiline telephone user hears ringing, a busy
tone, or call-waiting ringback while transferring a call. To use Camp-On to
complete the transfer, press a programmed Camp-On button or press the
Feature button and dial
the Feature button and select
Single-Line Telephones
Calls can be camped on to single-line telephones, but single-line telephone
users cannot use Camp-On.
