Calls in the Call-Waiting Queue
The system administrator can additionally configure and activate a Call-waiting queue for your telephone in
the Comfort Pro. While you are making a call, new calls are registered in this queue, the caller first hears an
announcement (if your system administrator has configured an announcement) and then the ring tone. The
number of calls that can be registered in your queue is defined by the system administrator, e.g. 5 calls. Once
this number is reached, any additional callers hear a busy signal. The calls in the queue are transferred in
accordance with their priority (baby calls, door calls, VIP calls, other internal and external calls), calls with the
same priority are transferred in the order made.
Calls that are in the queue for too long a time are removed. The caller then hears a busy signal also. The time
interval until an external call is cleared from the queue is defined by the network operator. This is usually
2 minutes in Germany and in other European countries usually 3 minutes.
Your telephone can have a call-waiting queue even if it belongs to a subscriber group. A call-waiting queue
simultaneously affects call forwarding.
N
Note: If call-waiting protection is activated on your telephone, every time a new call
comes in you will hear the call-waiting tone and see on your display whether the call is
external or internal. If call-waiting protection is activated and you end the call, the next
waiting call will be signalled.
For more information, please refer to the “Call Queue” chapter in the “Comfort Pro Mounting and
Commissioning” user guide.
Calls with Booking Numbers
By means of a booking number you can record the call data of a connection to an external subscriber and
save them in the Comfort Pro for further evaluation. Booking numbers are useful, e.g. for calculating costs per
client (fees and times) in an office. Incoming calls can also be associated with a booking number.
Notes on booking numbers
■
The system administrator defines the length of the entered booking number during system configuration.
■
Entering a booking number during a call is possible only if the system administrator has activated this
function for your user group.
