Speaker Calls
Speaker calls let you make calls to another tele-
phone’s speaker instead of ringing that telephone.
Note
Speaker calls (except Two-Way Speaker Call) will 
override Do Not Disturb, Forwarding, and Hunt 
Groups. (See “Do Not Disturb” on page 6–3, 
“Forwarding” on page 5–3, and “Hunt Groups” on 
page 7–7.)
Speaker calls can be blocked with the Speaker Call 
Rejection feature. (See “Speaker Call Rejection” on 
page 3–33.)
Fixed One-Way Speaker Call
The Fixed One-Way Speaker Call feature lets you 
make a one-way call to the speaker of a telephone that 
is set up at the CBX (fixed) as your speaker call target. 
The other party can hear you but must pick up the 
handset to answer. You may want to write the name 
of the person who is your speaker call target next to 
the Fixed One-Way Speaker Call (SPK1WYF) key on 
your telephone’s faceplate.

way speaker call

Begin speaking. The other party must pick up 
the handset to answer and will hear single beeps 
periodically until they do or until you hang up.
