Message Waiting

Description

For systems without voice mail, leave a Message Waiting request for a return call.

An extension user can leave a Message Waiting indication at a busy or unanswered extension requesting a return call. The indication is a flashing V-MAILkey and Ring/Message lamp at the called extension. Answer- ing the Message Waiting automatically calls the extension which left the indication. Message Waiting ensures that a user will not have to recall an unanswered extension. It also ensures that a user will not miss calls when their extension is busy or unattended.

An extension user can leave Messages Waiting at any number of extensions. Also, any number of extensions can leave a Message Waiting at the same extension. If an extension has multiple messages waiting, the user can scroll through their Messages Waiting and select a co-worker to call back.

Single Line Telephone Message Waiting

Message Wait Lamping

The system provides two types of Message Wait lamping at single line telephone ports: High Voltage and FSK (Frequency Shift Keying).

❥High Voltage Message Waiting

With High Voltage Message Waiting, the system switches the 150 VDC signal required to light the Mes- sage Waiting lamps on analog telephones with messages waiting. This type of lamping is typically used on conventional 2500 type sets with Message Waiting lamps. Check your system’s single line sets to see if they require High Voltage Message Waiting. High Voltage Message waiting is not available in DSX-40.

❥FSK Message Waiting

The system can alternately provide an FSK signal to light the Message Waiting lamp on an analog tele- phone. Instead of 150 VDC, FSK Message Waiting uses a modulated carrier signal to control lamping. This type of Message Wait signaling is typically used on new, electronic single line sets. Check your sys- tem’s single line sets to see if they require FSK Message Waiting.

SLT Special Dial Tone

Either type of Message Wait lamping can be used with SLT Special Dial Tone. When SLT Special Dial Tone is enabled, an SLT user with messages waiting hears a pulsating Intercom dial tone when they lift the handset. Intercom dial tone returns to normal only after the SLT user dials *8 to answer all their Messages Waiting.
