MWI

MWI = Message Waiting Indicator

Usually an audio or visual signal that a voicemail or other type of message is waiting. Examples:
  • Stutter dial-tone
  • Flashing light on phone
  • Vibration
  • Periodic special ring
  • etc.

Most IP phones support a MWI indicator, and most ATA's support stutter dial-tone.Asterisk also supports stutter tone on Zaptel FXS adapters.

The following ATA's can be configured to additionally light an LED on the base unit for MWI:
  • Grandstream HT488
  • Sipura SPA-3000
  • Linksys PAP-2

The following IP phones are known have trouble displaying MWI:
  • Budgetone BT-101/BT-102 claims to, but does not

Some analog phones also support MWI via a 90V neon lamp - requires hardware support on the FXS interface.Currently seems to only be supported by the Xorcom Astribank.
