Hunt groups provides functions of call processing center. The device is supported by 3 operation mode of
hunt groups: group, serial and cyclic.
In ‘group’ mode, the call will be sent to all the free group ports simultaneously. If one participant of call
group answers, the call to other ports is stopped.
In ‘serial’ mode call will be sent to the first free port in the list and, after specified timeout, the next free
port from the list will be added to the main port. When one of the group participants answers, the call to the
other free ports will be finished.
In ‘cycle’ mode the free participant of the group is searched by timeout. Thus, cyclical calls each after each
will be sent to all the free group ports.

Group – call group signal will be sent to all the ports of group simultaneously;
Serial – port number, that call will be forwarded to, will be increased by one when
zero value is defined for call timeout of the next port;
Cyclic – cadence through the interval, that is equal to timeout of the next port
calling, will be transmitted to each port of group cyclically;
– Next port calling timeout, sec – option is used by ‘serial’ and ’cyclic’
group types and option assigns time interval to switch a call to following
port(s);
– Call queue size – setting allows you to limit maximum number of unanswered calls to call group
queue. If the group has free port and unanswered calls, incoming call is not put on the queue.
