System Telephones
The Comfort Pro P 100, Comfort Pro P 300 and Comfort Pro P 500 are corded system telephones that you
can operate on your Comfort Pro communications system. The MenuCard display makes your telephone
easy to operate and gives you fast access to your system’s wide range of different functions and features.
The Comfort Pro P 100, Comfort Pro P 300 and Comfort Pro P 500 have the same functionality, the only
difference being the size of the display and the number of programmable keys available. Furthermore, the
Comfort Pro P 300 and Comfort Pro P 500 can be expanded by means of an add-on key extension with a
display, that offers additional programmable keys (see page 34).
The Comfort Pro P 300 and the Comfort Pro P 500 are also available as IP telephones (Comfort Pro P 300 IP
and Comfort Pro P 500 IP). These telephones have the same functionality as the standard system telephones.
All of the functions described in this guide are also available for the IP telephones. The chapter VoIP
Telephones starting on page 92 contains a short summary of the information necessary for the IP system
telephone user.
NN Note: The IP telephones Comfort Pro P 300 IP and Comfort Pro P 500 IP can only be operated on the Comfort Pro communications system.
You can activate the features and programme functions on the telephones themselves, or equally
conveniently, use the Configurator of the communications system.

This is for dialling call numbers or entering text. The key label does not show all the available letters and
special characters. For more information, refer to the section entitled Entering Text on page 31.
Trunk Key (Call Key 1)
g
The trunk key of the telephone (also: call key 1) is occupied by your internal call number (main number). The
key is located to the left of the display, and is labelled with your internal call number (or optionally, with a text
programmed by the system administrator). Refer to the respective illustration in the chapter Key Assignments
starting on page 14 to determine the position of the key on your equipment. Your internal call number is
assigned to an external call number where you can be reached when being called from an external number. It
is possible to assign several external call numbers to the key. If you wish to make a call, lifting the handset
seizes the key (and the trunk line); you can immediately dial an internal or external number (depending on the
system setting). Long pressing the key displays a MenuCard which allows you to programme the key’s
settings (see the section entitled MenuCard “Prog. call key” starting on page 132).
A system setting makes it possible to have your internal number assigned to other telephones as well. Calls
will then be signalled to other telephones simultaneously.
The LED of the key indicates the current status, see also the chapter Signalling on the Call Keys starting on
page 50.
For the System Administrator: Setting the Trunk Keys of the System Telephones
■The internal call number for a system telephone is configured in the Configurator, Telephony: Ports:
Upn menu or for IP phones respectively in the Configurator, Telephony: Devices: VoIP Phones menu.
The assigned internal call number is automatically allocated to the trunk key (call key 1).
■The assignment to external call numbers takes place in the Configurator, Telephony: Call Distribution
menu.
