• If any of the landing destinations answers the call before the expiry of the Built-In Auto Attendant Inactivity
Timer, the system stops the Built-In Auto Attendant Inactivity Timer and the Trunk Auto Answer Ring Back
Tone message, and connects the caller to the extension that answered the call.
• If none of the landing extensions answers the call before the expiry of the Built-In Auto Attendant Inactivity
Timer, the system plays the Trunk Auto Answer Busy Bye message and releases the trunk port.
If no Trunk Auto Answer Busy Bye message is assigned, the system plays the Busy Tone for the duration
of the Busy Tone Timer and releases the trunk port.
When Trunk Auto Answer–When Busy is enabled on a trunk, for each incoming call on the trunk,
• The System answers the call with the Trunk Auto Answer Greeting message and loads the Built-In Auto
Attendant Inactivity Timer.
The Greeting message is played once.
• The System waits for any of the landing destinations (Operator or Extensions) selected for the time of the
day to be free.
• If no landing destination is free at the end of the Trunk Auto Answer Greeting message, the system plays
Ring Back Tone or Trunk Auto Answer Ring Back Tone message, if assigned, to the caller for the duration
of the Built-In Auto Attendant Inactivity Timer.
• If any of the landing destinations is free before the expiry of the Built-In Auto Attendant Inactivity Timer, the
system places the call on that destination.
• If none of the landing destinations is free at the end of the Built-In Auto Attendant Inactivity Timer, the
system plays the Trunk Auto Answer Busy Bye message, if assigned, and releases the trunk port.
If the Busy Bye message is not assigned, the system will play the Busy Tone to the caller for the duration
of the Busy Tone Timer.
When Trunk Auto Answer–Delayed is enabled on a Trunk, for each incoming call on the trunk,
• The system first routes the incoming calls to the Extensions and waits for the duration of the Delayed Trunk
Auto Answer Timer (configurable; default:10 seconds) for any of the extensions to answer the call.
• If the call is not answered by any of the extensions, the System answers the call with a Greeting message,
known as the Trunk Auto Answer Greeting, and rings the landing destination selected for the time of the
day.
The system starts the Built-In Auto Attendant Inactivity Timer (default: 60 seconds). The Trunk Auto
Greeting message is played once. You may assign a Trunk Auto Answer Greeting of your preference.
• If the landing destination does not answer before the Trunk Auto Answer Greeting message ends, the
system plays Trunk Auto Answer Ring Back Tone message to the caller.
The Ring Back Tone message is played repeatedly for the duration of the Built-In Auto Attendant Inactivity
Timer.
However, if no Trunk Auto Answer Ring Back Tone message is assigned, the system plays Ring Back Tone
to the caller for the duration of this timer.
