Introduction Call Queue
Call Queue
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 T-Comfort 830 and Comfort Pro P 500 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 T-Comfort 830 and Comfort Pro P 500indicates 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 T-Comfort 930 DSL in the following order of priority: 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.

Note: As calling fax machines often operate with the “voice” service indicator (e.g. on
analogue ports), you should assign ports for fax machines on the T-Comfort 930 DSL
to a user group without a queue.
