Press to intrude
Intrusion tone is heard and a three-party call is established.
When the called extension replaces the handset and you keep off hook, the called extension will be recalled automatically.
If you still hear the busy tone, then your extension does not have the authority to intrude or the desired extension is protected against Intrusion.
Your phone can tell you the duration of your last call and display the total time of all external calls made.
