4. Message Waiting Indication (MWI)
If a voice message is left on the server for a subscriber, the service allows the subscriber to be timely
notified about the message. When the MWI service is enabled and there is a new message on the server, the
subscriber will hear a discontinuous buzzer when he picks up the phone.
In order to enable the MWI service, set the flag in the MWI field of the corresponding port on the VoIP/SIP
Advanced Setting tab (see section 4.3.2 SIP Advanced Settings submenu).
5. Call Barring
The service allows phone access restriction to a certain types of outgoing calls.
The service can be configured in the menu with user port settings in the VoIP/SIP Advanced Setting tab
(see section 4.3.2 SIP Advanced Settings submenu) by setting the Call barring flag and specifying the required
parameters in the Call barring mode and Call barring digit map fields.
Three options of calls restriction are available depending on the parameter specified in the Call barring
mode field:
 Allow all – all outgoing calls are allowed;
 Deny all – all outgoing calls are denied;
 Deny by digit map – denied are only the calls to the number specified in the Call barring digit map
field.
Service usage:
‘Call barring digit map’ value is 1150. In order to deny all outgoing calls, choose the Deny all option in the
Call barring mode field. In order to deny all calls to 1150, specify Deny by digit map in the Call barring mode
field.
