574 Matrix PRASAR UCS System Manual
Auto Attendant
What’s this?
Auto Attendant allows external callers to reach an extension directly without the intervention of the Operator.
If Auto Attendant is enabled on a trunk, whenever an external call lands on that trunk, the Voice Mail Auto Attendant
of PRASAR UCS greets and prompts the caller to dial the desired extension number. The call is then placed to the
extension number dialed by the caller.
PRASAR UCS offers Delayed Auto Attendant, whereby incoming calls routed to the Operator or the Trunk Landing
Group, can be answered by the Voice Mail Auto Attendant, if none of the landing extensions answers the call within
a certain time period.
Regular callers who know the extension numbers, can use the Auto Attendant to reach the desired extensions
without Operator assistance. Thus, this reduces the call traffic on the Operator extension, saves caller’s time for
call set-up and transfer. The Auto Attendant is particularly useful during non-working hours and holidays, and it
helps project a professional image of the organization.
How it works
Auto Attendant can be configured on the trunks, for the three time zones (working hours, break hours and non-
working hours).
Voice Mail Auto Attendant
PRASAR UCS supports 64 simultaneous VMS calls
81
. These calls can be made by extension users to access their
mailbox or incoming calls landing on a trunks that has Voice Mail Auto Attendant enabled.
If all channels are used by extension users, the external incoming calls on the Voice Mail Auto Attendant enabled
trunks remain unanswered. To make sure that the incoming calls on the trunks are answered you can reserve
channels of the VMS as per your requirement.
The extension users will not have access to the channels reserved for incoming calls on the trunks to access their
mailbox.
If all the reserved channels are busy and there is an incoming call on the trunk, it will land on the unreserved
channel if free.
To reserve a channel, see “Configuring VMS General Parameters”.
When the Voice Mail Auto Attendant of PRASAR UCS is selected as the destination for incoming calls on a trunk,
this is how it will work:
• A call lands on a Trunk.
• The Voice Mail System (VMS) answers the call.
81. For the VMS calls, the number of channels that will be supported would be as per the license you purchase.
