Cortelco 7150 Telephone User Manual


 
CALLER ID FEATURES
MESSAGE LIGHT
An indicator marked NEW CALL will light up to let you know when there are new calls
received.
If you have a voice mailbox service with your telephone company, another indicator
marked MESSAGE will flash to alert you to dial your telephone company to check your
new messages.
The MESSAGE indicator also monitors the unit’s situation. When the phone is in use, the
MESSAGE indicator will be on continuously. If the indicator is flashing quickly, it means
the phone is ringing. If it is not ringing and the light is flashing, the unit has experienced
a power outage.
MESSAGE WAITING
This units MESSAGE WAITING DETECTION is for both FSK and Stutter Tone Systems.
IF YOUR SERVICE IS FSK:
1. If you have a voice mailbox service from the phone company, the MESSAGE
indicator will flash and [MESSAGE WAITING] will appear on the display for 20
seconds when a message waiting on signal from the Central Office is received.
2. The MESSAGE indicator will go off and [MSG WAITING OFF] will appear for 20
seconds if the message waiting off signal is sent from the Central office.
IF YOU ARE IN AN AREA WHERE AN FSK SIGNAL IS NOT AVAILABLE:
1. This unit will check your line for a stutter dial tone every time you hang up or each
time a call goes unanswered. The MESSAGE indicator will flash when there is a
message waiting.
2. You may experience some delay in seeing the MESSAGE indicator light up even
though there are messages in your mail box. This delay is due to regulatory
matters and does not indicate a problem with the unit.
This unit may not be activated or deactivated under certain conditions. For example,
when you retrieve your message from an outside phone (not your own telephone
number), the MESSAGE indicator may not be canceled when you return home. If you
experience this situation, pick up the receiver and hang up. The MESSAGE indicator will
cancel.
