Cortelco 3719 Telephone User Manual


 
CALL WAITING DISPLAY
In the past, if you had call-waiting service, a tone alerted you there was a new call while you were on an existing call. Now our
Call Waiting Caller ID not only tells you there is another call waiting, but lets you know who the caller is before you answer it.
The call waiting information is shown on the display. The CALL WAITING (CW) symbol will flash for 16 seconds along with
the telephone number and name of the person who is on call waiting. Press the FLASH button to put the existing call on hold and
answer the new call.
Note: Whether or not you answer the call, the Call Waiting Caller ID will store the call information for future reference.
NOTE: MAKE SURE YOU HAVE SUBSCRIBED TO BOTH CALL WAITING CALLER ID AND CALLER ID SERVICE
FROM YOUR LOCAL TELEPHONE COMPANY. IF YOU ONLY HAVE CALLER ID SERVICE, THE UNIT WORKS
FOR CALLER ID ONLY.
MUTE BUTTON
Press MUTE to speak without the person on the phone hearing your conversation. The MUTE Indicator will appear (MIC
MUTED will flash in display) and remain until you resume your conversation. To resume your conversation, press MUTE.
The MUTE indicator will disappear and your call can continue.
RINGER VOLUME
Use the Ringer Volume control located on the right side of the phone base to change the ringer volume. The 3 position switch is
used to set ringer volume to OFF, LO, or HI. Remember to set the Ringer switch to LO or HI when you want to receive calls.
