Intrusion
If the called internal user B is busy, the internal user C has the possibility of intrud-
ing into the current call. User C hears the current call and has the possibility of talk-
ing to user B into whose call C has intruded. User A is not normally aware of this.
User B can choose to take C’s call (and put the original call on hold, end the original
call, set up a three-party conference) or reject it.

Detailed Description
Tab. 229 Intrusion
Note:
If the conference tone is deactivated in the system configuration, user B
will not hear an attention tone. The national terms and conditions for
data protection need to be observed in this respect.
If B is making an exchange all, intrusion will only work if this feature is also enabled
for exchange calls, throughout the system.
