Message Wait Indication on SIP Trunks
SETU VFXTH supports Message Wait Indication (MWI) on SIP Trunks for Voicemail service subscribed from
ITSPs.
If you have subscribed Voicemail service from the ITSP of a SIP Trunk, you can subscribe Message Wait Indication
for that SIP Trunk to get notification for new messages in your mailbox on the phone connected to an FXS Port.
You can retrieve messages from the phone connected to the FXS Port by dialing an access code. See “How to
Retrieve Messages” at the end of this topic.
You can also view the status of MWI on the SIP Trunks Status page on Jeeves. See “How to view Status of
Message Wait Indication” later in this topic.
To be able to use Message Wait Indication (MWI) for the voicemail service of the ITSP, you must do the following
configuration on the SIP Trunk and FXS Port:
On the SIP Trunk,
• Enable Subscribe for MWI flag.
• Configure the Message Retrieval Number.
• Assign the FXS Port on which you want to receive MWI notification from the SIP Trunk, as the destination
port to
Send MWI Notification on . Whenever a new message arrives in the mailbox of the SIP Trunk,
SETU VFXTH gives notification to the FXS Port you have selected as destination, according to the type of
Message Wait Notification you have selected on the FXS Port.
For configuration instructions, see “Message Wait Indication (MWI)” under “SIP Trunks” .
On the FXS Port selected as Destination for MWI,
• Select the Message Wait Notification Type. Whenever a new message arrives in the Mailbox of the SIP
Trunk, SETU VFXTH gives notification to the destination FXS Port according to the type of Message Wait
Notification set on the FXS Port. For instructions to select notification type, under the topic
“FXS Port” , see
“General” .
SETU VFXTH supports the following types of Message Wait Notification:
• Stuttered Dial Tone: To indicate new message, a stuttered dial tone will be played to the user when
the phone connected to the FXS Port goes off-hook. You can change the frequency and cadence of the
Stuttered Dial tone, if required. For instructions, see
“Call Progress Tones” .
• LED Lamp: If the phone connected to the FXS Port is equipped with a 'Message Wait' lamp, you can
set this type of Message Wait Notification. The lamp will blink continuously to indicate arrival of new
message. The lamp will be turned off after you have retrieved all the waiting messages.
• Ring: To indicate the arrival of a new message, the Message Wait Ring (Short, Fast) will be played on
the FXS Port. You can change the Message Wait Ring type, if required. For instructions, see “Region” .
The FXS Port will ring for the duration of the Message Wait Ring Timer (configurable; default: 30
seconds). If the ring is not answered within this timer by the FXS Port user, the system will ring again
