configure voip > gateway dtmf-supp-service supp-service-settings > enable-mwi

[EnableMWI]

Enables Message Waiting Indication (MWI).

■ [0] Disable (default)
■ [1] Enable

Note:

■ The parameter is applicable only to FXS interfaces.
■ The device supports only the receipt of SIP MWI NOTIFY messages (the device doesn't generate these messages).
■ For more information on MWI, see Message Waiting Indication.

'MWI Analog Lamp'

configure voip > gateway dtmf-supp-service supp-service-settings > mwi-analog-lamp

[MWIAnalogLamp]

Global parameter enabling the visual display of MWI.

You can also configure the feature per specific calls, using Tel Profiles ('MWI Analog Lamp' parameter). For a detailed description of the parameter and for configuring the feature in the Tel Profiles table, see Configuring Tel Profiles.

Note:

■ If the feature is configured for a specific Tel Profile, the settings of the global parameter is ignored for calls associated with the Tel Profile.
■ The parameter is applicable only to FXS interfaces.

'MWI Display'

configure voip > gateway dtmf-supp-service supp-service-settings > enable-mwi

[MWIDisplay]

Global parameter enabling the sending of MWI information to the phone display.

You can also configure the feature per specific calls, using Tel Profiles ('MWI Display' parameter). For a detailed description of the parameter and for configuring the feature in the Tel Profiles table, see Configuring Tel Profiles.

Note:

■ If the feature is configured for a specific Tel Profile, the settings of the global parameter is ignored for calls associated with the Tel Profile.
■ The parameter is applicable only to FXS interfaces.

'Subscribe to MWI'

configure voip > gateway dtmf-supp-service supp-service-settings > subscribe-to-mwi

[EnableMWISubscription]

Enables subscription to an MWI server.

■ [0] No (default)
■ [1] Yes

Note:

■ To configure the MWI server address, use the [MWIServerIP] parameter.
■ To configure whether the device subscribes per endpoint or per the entire device, use the parameter [SubscriptionMode].

'MWI Server IP Address'

configure voip > gateway dtmf-supp-service supp-service-settings > mwi-srvr-ip-addr

[MWIServerIP]

Defines the MWI server's IP address. If provided, the device subscribes to this IP address. The MWI server address can be configured as a numerical IP address or as a domain name. If not configured, the Proxy IP address is used instead.

'MWI Server Transport Type'

configure voip > gateway dtmf-supp-service supp-service-settings > mwi-srvr-transp-type

[MWIServerTransportType]

Defines the transport layer used for outgoing SIP dialogs initiated by the device to the MWI server.

■ [-1] Not Configured (default)
■ [0] UDP
■ [1] TCP
■ [2] TLS

Note: When set to ‘Not Configured’, the value of the parameter [SIPTransportType] is used.

'MWI Subscribe Expiration Time'

configure voip > gateway dtmf-supp-service supp-service-settings > mwi-subs-expr-time

[MWIExpirationTime]

Defines the MWI subscription expiration time in seconds.

The default is 7200 seconds. The range is 10 to 2,000,000.

'MWI Subscribe Retry Time'

configure voip > gateway dtmf-supp-service supp-service-settings > mwi-subs-rtry-time

[SubscribeRetryTime]

Defines the subscription retry time (in seconds) after last subscription failure.

The default is 120 seconds. The range is 10 to 2,000,000.

'Subscription Mode'

configure voip > sip-definition proxy-and-registration > subscription-mode

[SubscriptionMode]

Defines the method the device uses to subscribe to an MWI server.

■ [0] Per Endpoint = (Default) Each endpoint subscribes separately - typically used for FXS interfaces.
■ [1] Per Gateway = Single subscription for the entire device - typically used for FXO interfaces.

configure voip > interface fxs-fxo > etsi-vmwi-type-one-standard

[ETSIVMWITypeOneStandard]

Defines the ETSI Visual Message Waiting Indication (VMWI) Type 1 sub-standard.

■ [0] = (Default) ETSI VMWI between rings
■ [1] = ETSI VMWI before ring DT_AS
■ [2] = ETSI VMWI before ring RP_AS
■ [3] = ETSI VMWI before ring LR_DT_AS
■ [4] = ETSI VMWI not ring related DT_AS
■ [5] = ETSI VMWI not ring related RP_AS
■ [6] = ETSI VMWI not ring related LR_DT_AS

Note: For the parameter to take effect, a device restart is required.

configure voip > interface fxs-fxo > bellcore-vmwi-type-one-standard

[BellcoreVMWITypeOneStandard]

Defines the Bellcore VMWI sub-standard.

■ [0] = (Default) Between rings.
■ [1] = Not ring related.

Note: For the parameter to take effect, a device restart is required.
