Auerswald/FONtevo VoIP system phones and standard VoIP phones
On standard VoIP phones, the LED of a function key assigned to MWI is
used for signalling (optional, see the phone manual).
If operated as a system phone, the LED of the message key is used for
signalling (optional, see the phone manual).
Auerswald IP DECT phones
The symbol on the display is used for signalling on COMfortel M-100, M-
200, M-210, M-300 and M-310 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
