To call/monitor a door phone
1. With the handset off-hook, press an extension button. You hear dial tone and the LED flashes green 

(in-use).

2. Press 

#15

 (hear three tone bursts), then enter the door phone number (01~24, depending on system 

size). A two-way talk-path exists between your telephone and the door phone. The door phone will 

not ring. You can audibly monitor the area around the door phone.

To call from a door phone
1. Press the door phone button and then release it. You hear a distinctive ringing tone–one or five times 

(set in system programming).

2. When answered, speak at a normal voice level in the direction of the door phone.

If a station remains off-hook for a programmable period, it can be automatically treated as an 

Emergency Call and directed to an emergency destination. The station may have partially dialled a 

number or have dialled no digits at all. Each station is programmed with its specific emergency 

ringdown destination.
A station number or a group pilot number can be specified as an emergency ringdown destination. In 

a private network, the station or pilot number must be in the same network node. Remote emergency 

destination and door phones are not permitted.

This feature enables you to change the language sent from the Attendant Console or from a PC. See 

your CTX System Administrator to find out if your telephone is programmed with the ability to 

change languages.
