Message Waiting Lamps

The following applies to both Callpilot and Meridian Mail.

Message Waiting (LD 10/11):

• MWD Message Waiting Denied (default)
• MWA Message Waiting Allowed

Analog (LD 10):

• LPD Message Waiting Lamp Denied (default)
• LPA Message Waiting Lamp Allowed

CLS = LPD MWA enables a stuttered dial-tone message waiting indication on analog sets.
If a modem/fax is connected to a message waiting line card port, that TN should be configured as LPD to prevent damage.

Digital (LD 11):

• MWTD Message Waiting Tone Denied (default)
• MWTA Message Waiting Tone Allowed (applicable for IP phones only)

Message Waiting Key (LD 11):

KEY xx MWK yyyy
Where: yyyy = Message center (CallPilot) DN.

Note:	M3902: key 5 is reserved for MWK or NUL.
	M3903/4/5 & i2004: key 16 is reserved for MWK or NUL.

If CLS = MWA and no Message Waiting Key (MWK) is defined, the red Message Waiting LED lights to indicate Message Waiting.
With an MWK key, the triangle next to the key will also illuminate. Press the key to call the message center and retrieve the message.

Clearing Stuck Lamp(s):

Program a set, perhaps in the PBX room, with a MCK (Message Cancellation) key. Press this key, and enter the DN of the set with a stuck on message waiting lamp, and press again. The users lamp should go out (incidentally, MIK turns a lamp on in the same way).

If a user complains his message waiting lamp lights seemingly randomly, check:

1. If other DN's appear on the TN, if any of those DN's have a voicemail waiting.
2. If another user is set to light his lamp with an Advanced Search in Voicemail Administration.

Testing a Message Waiting lamp using MIC and MCK keys:

• To turn ON a Message Waiting lamp:
  1. Hit the MsgInd (MIK) key, it will stay solid
  2. Enter the DN with the MW lamp to light
  3. The MsgInd key will clear and the MW lamp on the DN will light.

• To turn OFF a Message Waiting lamp:
  1. Hit the MsgCancel (MCK) key, it will stay solid
  2. Enter the DN with the MW lamp to turn off
  3. If the lamp is lit, the MsgCancel key will flash
  4. Press the MsgCancel key again and the MW lamp on the DN will go out.

Check Message Waiting lamp status:

In LD 80, type:

• TRAC l s c u 16 to show the status of the message key (16), or:
• TRAC l s c u to show all the keys

If the MIK key doesn't light the lamp (with LPA and MWA in sets CLS), suspect a hardware issue. The MW voltage is typically about 90 volts DC, and pulses on and off (flashes). It can be measured at the TN, or heard as a ticking sound with a butt set in monitor mode.
