1.7 Busy Line/Busy Party Features
1.7.1 Automatic Callback Busy (Camp-on)
If the dialled extension or outside (CO) line is busy when a call is made, the caller can choose to be informed by a callback ring (Camp-on Recall) when the extension or outside (CO) line becomes free.
When the user answers the callback ring: |
| For an intercom call: The called extension starts ringing without the user having to redial. |
| For an outside (CO) line call: The line is seized. |
| • |
If the callback ring is not answered within 10 seconds (4 rings), the callback is cancelled. |
| • |
More than one extension user can set this feature to monitor the same destination extension or outside (CO) line at the same time. |
1.7.2 Executive Busy Override
| An extension user can interrupt an existing call to establish a 3-party conference call. |
Executive Busy Override Deny
It is possible for extension users to prevent their calls from being interrupted by another extension user. |
| • |
System programming determines extension users who can use Executive Busy Override ( Executive Busy Override [608]). |
| • |
This feature will not function when the busy extension has set Executive Busy Override Deny or Data Line Security ( 1.10.5 Data Line Security). |
| • |
When a 2-party conversation is changed to a 3-party conference call, a confirmation tone will be sent to all parties ( 1.13.1.2 Conference). It is possible to eliminate the tone through system programming ( Conference Tone [105]). |
1.7.3 Call Waiting Tone
| When an extension user attempts to call a busy extension (i.e., an extension that is ringing or having a conversation), a call waiting tone will be sent to the called extension to indicate another call is waiting. |
| • |
This feature functions only if the called extension has activated Call Waiting. If it is activated, the calling extension will hear a ringback tone. |
| • |
One of 2 call waiting tones can be selected through personal programming (Call Waiting Tone Type Selection). |
