and then returns to idle, the callback is handled in the same way as Callback Busy. Up to 100
Callback requests may be active within the system at any time; however, a maximum of only
25 ARS Callbacks is permitted in these requests.
Campon
The Campon feature allows a device to indicate to a busy party that communication is desired,
and to be connected when the party is free. Also, the user can make a continuing request for
a trunk when the trunk group is busy, and be connected to a trunk when one becomes free.
If, when calling an extension, hunt group, or ARS, the destination is busy, the caller usually
receives a tone for a predefined period and then camps on to the busy device. The type of tone
indicates whether or not campon is allowed during the period, or is available at the end of the
period. For some calls the period is skipped.
The busy called extension receives a tone alerting the party that there is a call waiting. See
Campon Warning Tone. An extension can consult the first waiting party using the Swap
Campon feature.
Campon may be initiated on a trunk group that has been programmed to give the Expensive
Route Warning. See Expensive Route Warning.
For recall from Campon, see Recall.
Campon Priority Over Call Forward Busy
If an internal call to a set that is busy and has Call Forward - Busy (or Call Forward - Busy/No
Answer) activated, the call is immediately forwarded. With this feature, the caller has the option
of camping on to the busy set or allowing the forward to take place.
Campon Warning Tone
When a device sets Campon to an extension or hunt group, a warning tone is sent to the
extension user over the current call. The warning tone can be programmed to repeat every 5
to 15 seconds.
Centralized Attendant
The Centralized Attendant feature allows an attendant or Subattendant on a system to answer
calls that arrive at another interconnected system. This feature is a purchasable option and
accompanies Centralized Voice Mail.
CENTREX Compatibility (Double Flash Over Trunk)
This feature provides the ability to send a double switchhook flash out over a trunk. Flashing
over a trunk allows for the use of CENTREX features by telephones within the system. Callers
must follow the instructions specified by the local central office concerning the use of double
flash.
