Message Waiting Indicator
This chapter explains how to set the Mediatrix 4104 to use the Message Waiting Indicator service.
You can also set these parameters via the web interface, as described in
“Message Waiting Indicator” on
What is Message Waiting Indicator (MWI)?
The Message Waiting Indicator (MWI) service alerts the user when new messages have been recorded on a
voice mailbox.
When the user receives a call and does not answer, the notification mechanism detects this situation and starts
the auto attendant. The caller can then leave a message.
After the message is recorded, the server sends a message to the Mediatrix 4104 listing how many new and
old messages are available. The Mediatrix 4104 alerts the user of the new message in two different ways:
The telephone’s LED blinks (if present).
A message waiting stutter dial tone replaces the normal dial tone when the user picks up the
first line.
Standard MWI Methods
The Mediatrix 4104 supports two MWI methods.
MWI Method #1
The Mediatrix 4104 sends SUBSCRIBE requests to the server for each line, unless there is no subscription
address defined. The Mediatrix 4104 then waits for NOTIFY requests containing the relevant message waiting
information.
To configure the MWI:
1.
In the
mwiMIB
, set the notification mechanism server address to which the Mediatrix 4104
subscribes in the
mwiConfigUserSubscriptionAddress
variable.
This mechanism notifies the Mediatrix 4104 when new messages are available. The address is a
SIP URL such as “scheme:user@host”. For instance, “sip:[email protected]”.
Because this variable is located in a table, you can define a different address for each line of the
Mediatrix 4104.
Note:
The message waiting state does not affect the Second Line feature. When in an active call,
performing a flash-hook to get access to the second line plays the usual dial tone.
