Voice Processing System Applications as Announcement/Overflow Stations

Announcement Endpoints: When a call rings in or is transferred to a hunt group, the
Announcement and Recall timers are started. The incoming call circulates through the hunt
group until it is answered or the Announcement timer expires. When this timer expires, the
unanswered call is picked up by the designated announcement endpoint which is a playback
device that answers the call and plays a message. Meanwhile, the call continues circulating
through the hunt group (unless it was sent to a voice processing system application and then
transferred to an endpoint). If it is answered by an available hunt group endpoint while the
announcement station is connected to the call, the call will leave the announcement station.
Each direct ring-in call will transfer to the announcement endpoint only once. If it remains
unanswered when the Overflow timer expires, the call will be sent to the overflow station. Or,
if there is no overflow station, the call will be sent to the recall destination endpoint when the
Recall timer expires.

Overflow Endpoints: The Overflow timer is started when the Announcement timer expires or,
if there is no announcement endpoint, when the call is received by the hunt group. If an incom-
ing hunt group call is unanswered when the Overflow timer expires, the call is picked up by an
overflow station. The overflow station is a playback device that answers the call and plays a
message. 

Meanwhile, the call continues circulating through the hunt group (unless it was sent to a voice
processing system application and then transferred to a endpoint). If the call is answered by an
available hunt group endpoint while the overflow station is connected to the call, the call will
leave the overflow station. The Overflow timer restarts each time the unanswered call leaves
the endpoint at the overflow station. An unanswered call will return to the overflow station
each time the Overflow timer expires, until the call is answered by a hunt group station or it is
sent to the recall destination station.

The following table shows the path that an incoming hunt group call follows for possible com-
binations of announcement and overflow stations:

If an announcement or overflow station has Call Forward enabled, hunt group calls will follow
the forward, and the forwarding destination endpoint will act as the announcement or overflow
station. 

When a voice processing system application is used as an announcement or overflow station,
calls to the application automatically stop circulating through the hunt group if the caller
selects a valid digit translation option (such as pressing a digit to select an extension from a
Call Routing Announcement menu), and the call is transferred. This allows the application to
send the call to other endpoints without the call being “pulled back” into the hunt group when a
