Figure 97 Breaking into a local system call path
Break-in can occur when these situations are valid:
• Target system telephone is busy but still has a free intercom or line key.
• There is no camped call on the target telephone.
• DND on busy is turned on.
• prime set is also busy, with no free key, and with DND turned on.
• Attendant capability is high (2), and higher than either the target telephone or the caller the
target telephone owner is busy with.
Only post-dial break-in is supported by MCDN:
1 Attendant dials destination number.
2 If a busy tone is heard, the attendant presses the BKI button.
Attendant is given access to the conversation.
You can set a level of priority that will determine if a telephone will allow an attendant to break in.
This is referred to as setting the Intrusion level. Use the following rules to configure the break-in
feature.
• Set the Intrusion level for each telephone (under Capabilities on the DN record). Refer to
“Capabilities tab” in the Device Configuration Guide (NN40020-300).
How the intrusion hierarchy works:
— Break-in is allowed if Attendant telephone is High and caller telephone is Medium.
— Break-in is not allowed if Attendant telephone is Medium and caller telephone is high.
