Ringing Patterns
You can tell what kind of call you are receiving by the way your telephone rings.
A single ring (ring . . . ring . . . ring . . .) means that you are receiving an
outside call.
A ring and a beep (ring BEEP . . . ring BEEP . . . ring BEEP . . .) means
that someone is calling you from another extension. If you have a system
phone with a display, the caller’s extension number will show on the
display.
A ring and two beeps (ring BEEP BEEP . . . ring BEEP BEEP . . . ring
BEEP BEEP . . .) means either that a transferred call is coming in, or that a
transferred call that was not answered is ringing back.
NOTE:
If you use the system with PBX or Centrex lines, the PBX/Centrex ringing
patterns are not passed to phones. Phones use the ringing patterns described
here instead.
Dial Tones
You will encounter two different dial tones when calling with a system phone:
Outside dial tone
is generated by your local phone company to indicate
that you are connected with an outside line.
Intercom dial tone
is generated by the system to indicate that you are
connected with an inside line. You hear this dial tone when you are
making an inside, or intercom, call.
To hear the difference between the two types of dial tones on a system phone,
press a line button. The dial tone you hear is an outside dial tone. To hear an
intercom dial tone, press [
Intercom
].
Using the Handset, Speaker, and Microphone
Every MLS-model telephone has a speaker, which you can turn on by pressing
[
Spkr
]. When the green light next to [
Spkr
] is on, the speaker is on.
MLS-34D, MLS-18D, MLS-12D, and MLS-12 phones also have a microphone.
On these phones, pressing [
Spkr
] turns on both the speaker and the
microphone. In addition, you can turn just the microphone on and off by
pressing [
Mic
]. When the green light next to [
Mic
] is on, the microphone is on.
If you prefer to dial and conduct calls without lifting the handset, you can use
the speaker and the microphone instead. Use these techniques to make calls
with the speaker and the microphone (if you have one):
To make a call without lifting the handset, press [
Spkr
] to get a dial tone;
then dial the number and you will hear the call ringing. When the other
party answers, you can talk without lifting the handset. On MLS-6 phones
(which have no microphone), you must lift the handset to talk when the
other party answers.
