Call Queue Introduction

11. Call Queue
11.1 Introduction
A queue can be activated for the telephone numbers of any type of telephone. 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 Aastra 6775ip (OpenPhone 75 IP) system telephone, additional calls are sig-
nalled 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 Aastra
6775ip (OpenPhone 75 IP) indicates how full the queue is. If more than one tele-
phone number with a queue is configured on the telephone, the total number of
entries are displayed.
Calls in a queue are handled by the Aastra 800 in the following order of priority:
instant connection, automatic recalls, VIP calls, then other internal and external
calls. 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.
