Ringing Patterns

You can tell the type of call coming in by the way the phone rings:

Ring...Ring...Ring...Ring...Ring...Ring... Outside Call

Ring-BEEP...Ring-BEEP...Ring-BEEP... Inside Call

Ring-BEEP-BEEP...Ring-BEEP-BEEP... Transferred Call

If Unique Line Ringing is active, all incoming outside calls on MLS- model phones ring as follows:

■Line 1—pattern described above.

■Line 2—ascending tone with dip.

■Line 3—descending tone.

■Line 4—mixed tone.

Outside calls transferred to your extension ring with the appropriate Unique Line Ringing pattern followed by two beeps.
