Voice Mail Parameters

Enables the device's Voice Mail application and determines the communication method between the device and PBX.

Note: To disable voice mail per Trunk Group, you can use a Tel Profile with the EnableVoiceMailDelay parameter set to disabled (0). This eliminates the phenomenon of call delay on Trunks not implementing voice mail when voice mail is enabled using this global parameter.

Enables the interworking of target and cause for redirection from Tel to IP and vice versa, according to RFC 4468.

Digital interfaces: Upon receipt of an ISDN Setup message with Redirect values, the device maps the Redirect phone number to the SIP 'target' parameter and the Redirect number reason to the SIP 'cause' parameter in the Request-URI.

Redirecting Reason >> SIP Response Code

Unknown >> 404

User busy >> 486

No reply >> 408

Deflection >> 487/480

Unconditional >> 302

Others >> 302

If the device receives a Request-URI that includes a 'target' and 'cause' parameter, the 'target' is mapped to the Redirect phone number and the 'cause' is mapped to the Redirect number reason.

Defines the time (in msec) that the device waits to detect busy and/or reorder tones. This feature is used for semi-supervised PBX call transfers (i.e., the LineTransferMode parameter is set to 2).

The valid value range is 0 to 20000 (i.e., 20 sec). The default is 2000 (i.e., 2 sec).

Defines the call transfer method used by the device. The parameter is applicable to the following:

The valid values are:

Enables Simplified Message Desk Interface (SMDI) interface on the device.

Note:

Defines the time (in msec) that the device waits for an SMDI Call Status message before or after a Setup message is received. The parameter synchronizes the SMDI and analog CAS interfaces.

If the timeout expires and only an SMDI message is received, the SMDI message is dropped. If the timeout expires and only a Setup message is received, the call is established.

The valid range is 0 to 10000 (i.e., 10 seconds). The default is 2000.

Defines the digit code used by the device to notify the PBX that there are no messages waiting for a specific extension. This code is added as prefix to the dialed number.
The valid range is a 25-character string.

Defines the digit code used by the device to notify the PBX of messages waiting for a specific extension. This code is added as prefix to the dialed number.
The valid range is a 25-character string.

Defines the digit code used by the device as a suffix for 'MWI On Digit Pattern' and 'MWI Off Digit Pattern'. This suffix is added to the generated DTMF string after the extension number.
The valid range is a 25-character string.

Defines the calling party's phone number used in the Q.931 MWI Setup message to PSTN. If not configured, the channel's phone number is used as the calling number.

Defines the IP Group ID used when subscribing to an MWI server. The 'The SIP Group Name' field value of the IP Groups table is used as the Request-URI host name in the outgoing MWI SIP SUBSCRIBE message. The request is sent to the IP address defined for the Proxy Set that is associated with the IP Group. The Proxy Set's capabilities such as proxy redundancy and load balancing are also applied to the message.

For example, if the 'SIP Group Name' field of the IP Group is set to "company.com", the device sends the following SUBSCRIBE message:

SUBSCRIBE sip:company.com...

Instead of:

SUBSCRIBE sip:10.33.10.10...

Note: If the parameter is not configured, the MWI SUBSCRIBE message is sent to the MWI server as defined by the MWIServerIP parameter.

Defines the IP Group ID to which the device sends SIP NOTIFY MWI messages.

Note:

Defines the Message Centred ID party number used for QSIG MWI messages. If not configured (default), the parameter is not included in MWI (activate and deactivate) QSIG messages.
The valid value is a string.

Defines the digit pattern used by the PBX to indicate 'call forward on busy' when the original call is received from an internal extension.

The valid range is a 120-character string.

Defines the digit pattern used by the PBX to indicate 'call forward on no answer' when the original call is received from an internal extension.

The valid range is a 120-character string.

Defines the digit pattern used by the PBX to indicate 'call forward on do not disturb' when the original call is received from an internal extension.

The valid range is a 120-character string.

Defines the digit pattern used by the PBX to indicate 'call forward with no reason' when the original call is received from an internal extension.

The valid range is a 120-character string.

Defines the digit pattern used by the PBX to indicate 'call forward on busy' when the original call is received from an external line (not an internal extension).

The valid range is a 120-character string.

Defines the digit pattern used by the PBX to indicate 'call forward on no answer' when the original call is received from an external line (not an internal extension).

The valid range is a 120-character string.

Defines the digit pattern used by the PBX to indicate 'call forward on do not disturb' when the original call is received from an external line (not an internal extension).

The valid range is a 120-character string.

Defines the digit pattern used by the PBX to indicate 'call forward with no reason' when the original call is received from an external line (not an internal extension).

The valid range is a 120-character string.

Defines the digit pattern used by the PBX to indicate an internal call.

The valid range is a 120-character string.

Defines the digit pattern used by the PBX to indicate an external call.

The valid range is a 120-character string.

Defines a digit pattern that when received from the Tel side, indicates the device to disconnect the call.

The valid range is a 25-character string.
