Call Queue

Introduction

15. Call Queue
15.1 Introduction
A queue can be activated for the telephone numbers of any type of telephone, i.e.
for system, analogue, ISDN and DECT telephones.
If a call number with a queue is busy, calls to this number enter the queue. The
caller first hears an announcement (if function "Announcer at busy" is configured)
and then a dial tone.
Calls which remain in the queue for too long are cleared from the queue. The caller
then gets a busy tone. If all the positions in the queue are taken then any further
calls also hear the busy tone.
The time until an external call is cleared from a queue is defined by the network
operator. In Germany this is usually two minutes and in other European countries
usually three minutes.
If more than one telephone number (e.g. trunk or team keys) has been configured
for a telephone, separate queues are used for each number.
On the OpenPhone 65 system telephone, additional calls are signalled by a brief
tone in the loudspeaker and in the display. If calls are in the queue, a number at
the beginning of the second line of the display on the OpenPhone 65 indicates
how full the queue is. If more than one telephone number with a queue is confi-
gured on the telephone, the total number of entries are displayed.
Calls in a queue are handled by the OpenCom 510 in the following order of pri-
ority: instant connection, door calls, automatic recalls, VIP calls, then other internal
and external calls. Sensor calls thus have priority over other calls, for example. Calls
of the same priority level are switched in the order of their arrival.
The system administrator sets the number of calls that can be placed in a queue
individually for each user group. The value can lie between "0" and "99". The "0"
value deactivates the "Call queue" function for a user group. When the maximum
number of calls in the queue is reached, further callers hear a busy tone.
Only calls which have a "voice" service indicator are administered in a queue.
