Matrix PRASAR UCS System Manual 581
Auto Call Back request set by you will be cleared by the system if:
• it was successfully served, that is, your extension was connected to the remote extension or the trunk you
were trying to reach.
• you do not answer the Auto Call Back ring, before the expiry of the Ring Timer, that is, within 30 seconds
(default setting).
• the remote extension does not answer the Auto Call Back ring before the expiry of the Ring Timer.
• it has not been served within 60 minutes.
Auto Call Back works for internal calls and for accessing trunk ports only.
How to configure
Auto Call Back is a Class-of-Service dependent feature. An extension user can set/cancel Auto Call Back only if it
is enabled in the extension's Class of Service.
The only configuration involved in this feature is enabling/disabling Auto Call Back in the Class of Service and
changing the duration of the Auto Call Back Ring Timer, if required.
Both these can be programmed using Jeeves.
Configuring Auto Call Back using Jeeves
By default, Station Basic Feature Template Number 01 is assigned to all extensions of PRASAR UCS. Station
Basic Feature Template 01 has the features 'Auto Call Back Busy' and 'Auto Call Back No Reply' enabled in the
default CoS group 01. So, all extensions of the PRASAR UCS can set/cancel Auto Call Back if the called number is
busy or does not reply.
However, if Auto Call Back Busy/No Reply is to be denied to any of the extensions, follow these steps:
1. Define a CoS group with Auto Call Back Busy/No Reply disable.
2. Prepare a Station Basic Feature Template with this CoS group applicable in all the “Time Zones”.
3. Assign this new Template to the selected extensions to which Auto Call Back is to be denied.
Refer the topics “Class of Service (COS)” and “Station Basic Feature Template” for instructions on how to
enable/disable a feature in a CoS group, how to prepare a Station Basic Feature Template with a new CoS
group and assign the new template to SIP extensions using Jeeves.
If the user wants to increase or decrease the duration of the of the Auto Call Back ring on both extensions, that
is, the extension requesting Auto Call Back and the destination extension, configure the 'Auto Call Back Ring
Timer', according to user preference.
