MWI (Message Waiting Indication) is a SIP function which allows to signal the presence of new
voice and fax messages on internal VoIP end devices. Signalling is possible for all voice mail
and fax boxes for which the subscriber in question is entered as user.
You can use this function with the following VoIP end devices:
Auerswald VoIP system telephones and standard VoIP telephones
On standard VoIP telephones, the LED of a function key assigned to MWI is used for signalling
(optional, see the telephone manual).
If operated as a system telephone, the LED of the message key is used for signalling (optional,
see the telephone manual).
Auerswald IP DECT telephones
The symbol on the display is used for signalling on COMfortel M-100, M-200 and M-300
handsets.
The function can be configured using the configuration manager of the IP DECT servers
COMfortel WS-400 IP or COMfortel WS-650 IP, on th page Configuration > SIP under
Message waiting indication (see the IP DECT server manual).
Standard VoIP end devices of other vendors
As precondition to support the MWI function, the SIP convenience package must have been
unlocked (optional, see chapter Important Information > Product Details > Basic Assembly and
Extensions).
Signalling and configuration depend on the end device (see the end device manual).
