Parameter Description
Subscribe to MWI
[EnableMWISubscription]
Disable [0] = Disable MWI subscription (default).
Enable
[1] = Enable subscription to MWI (to MWIServerIP address).
Note: Use the parameter ‘SubscriptionMode’ (described in Table 5-35 on page
132) to determine whether the gateway subscribes separately per endpoint of for
the entire gateway.
MWI Server IP Address
[MWIServerIP]
MWI server IP address. If provided, the gateway subscribes to this IP 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 Subscribe Expiration
Time
[MWIExpirationTime]
MWI subscription expiration time in seconds.
The default is 7200 seconds. The range is 10 to 72000.
MWI Subscribe Retry Time
[SubscribeRetryTime]
Subscription retry time in seconds.
The default is 120 seconds. The range is 10 to 7200.
Stutter Tone Duration
[StutterToneDuration]
Duration (in msec) of the played Stutter dial tone, which indicates that Call
Forwarding is enabled or that there is a waiting message(s).
The default is 2,000 (i.e., 2 seconds). The range is 1,000 to 60,000.
The Stutter tone is played (instead of a regular Dial tone), when a Call Forward is
enabled on the specific port or when MWI is received. The tone is composed of a
‘Confirmation tone’, which is played for a user-defined duration
(StutterToneDuration), followed by a ‘Stutter tone’. Both tones are defined in the
CPT file.
Note 1: This parameter is applicable only to FXS gateways.
Note 2: The message waiting notification (MWI) tone takes precedence over the
call forwarding reminder tone.
For detailed information on Message Waiting Indication (MWI), refer to Section
8.1.6 on page 218.
Conference Parameters
Enable 3-Way Conference
[Enable3WayConference]
Enables or disables the 3-Way Conference feature.
Valid options include:
Disable
[0] = Disables 3-way conference feature (default)
Enable
[1] = Enables 3-way conference feature
Establish Conference Code
[ConferenceCode]
Defines the digit pattern that once detected, generates the Conference-initiating
INVITE when Enable3WayConference is set to 1.
The valid range is a 25-character string. The default is “!” (Hook-Flash).
Conference ID
[ConferenceID]
Defines the Conference Identification string (up to 16 characters). The gateway
uses this identifier in the Conference-initiating INVITE that is sent to the media
server when Enable3WayConferenceis set to 1.
The default value is ‘conf’.
For example: ConferenceID = MyConference.
5.5.2.3 Metering Tones
FXS gateways can generate 12/16 KHz metering pulses towards the Tel side (e.g., for
connection to a payphone or private meter). Tariff pulse rate is determined according to an
internal table. This capability enables users to define different tariffs according to the
Source / Destination numbers and the Time-of-Day. The tariff rate includes the time interval
between the generated pulses and the number of pulses generated on answer.
