3.28.1.1 DESCRIPTION
A user is automatically camped-on on a station he is calling when the following conditions are
met:
- it is busy (in conversation with a party)
- it has at least one resource free (see "Resource keys" file)
- it is not protected against camp-on
- the caller is authorized to camp-on
A user is automatically camped-on a Hunt Group which he is calling when the following
conditions are met:
- all the stations in the group are busy, i.e. in conversation with a party
- at least one of the stations in the group has a free resource (see "Resource keys" file)
- the stations in the group are not protected against camp-on
- the caller is authorized to camp-on
A camped-on caller can:
- Release the call, possibly leaving a text message (see "Text mail/Callback request")
- leave an automatic callback request with the called party, if the station supports
- intrusion into the existing conversation, if the caller is authorized and if the station is not
protected against intrusion
- transfer his PARTY if on-hold (see "Conference")
3.28.1.2 ADDITIONAL INFORMATION
- When camp-on is allowed and the called party is not protected against the camp-on tone,
the camped caller hears the camp-on tone and the called party hears a single beep every
20 seconds.
- If the automatic callback request is accepted, the user hears the dial tone if he is off hook
and switches to the idle status in hands-free mode.
- An authorized station can only request a single automatic callback at a time.
- A station can only receive a single automatic callback request at a time.
- A callback request does not follow a call forwarding.
- The identity of the barging in station is displayed on the stations which are already in
conversation.
- Barge-in is refused (the user then remains camped-on) if:
• the called party is in a conference call
• the called party is barging in on another conversation
• at least one of the stations is protected against barge-in
- An attendant station always has the authority to camp on and to barge-in.
- When the user is barging in while having a party on hold, he returns to this party by
canceling the barge-in and disconnecting going on hook and returning to the call on hold.
- The first analog (Z) station is considered as a fax and is therefore protected by default
