Voice Mail Parameters

The voice mail parameters are described in the table below. For more information on the Voice Mail application, refer to the CPE Configuration Guide for Voice Mail.

Voice Mail Parameters

Parameter

Description

'Voice Mail Interface'

configure voip > gateway voice-mail-setting > vm-interface

[VoiceMailInterface]

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

[0] None (default)
[1] DTMF
[2] SMDI
[3] QSIG
[4] SETUP Only = Applicable only to ISDN.
[5] MATRA/AASTRA QSIG
[6] QSIG SIEMENS = QSIG MWI activate and deactivate messages include Siemens Manufacturer Specific Information (MSI)
[8] ETSI = Euro ISDN, according to ETS 300 745-1 V1.2.4, section 9.5.1.1. Enables MWI interworking from IP to Tel .
[9] NI2 = ISDN PRI trunks set to NI-2. This is used for interworking the SIP Message Waiting Indication (MWI) NOTIFY message to ISDN PRI NI-2 Message Waiting Notification (MWN) that is sent in the ISDN Facility IE message. This option is applicable when the device is connected to a PBX through an ISDN PRI trunk configured to NI-2.

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.

'Enable VoiceMail URI'

voicemail-uri

[EnableVMURI]

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

[0] Disable (default)
[1] Enable

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.

[WaitForBusyTime]

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).

'Line Transfer Mode'

configure voip > gateway voice-mail-setting > line-transfer-mode

[LineTransferMode]

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

Digital interfaces: E1/T1 CAS call transfer if the TrunkTransferMode_x parameter is set to 3 (CAS Normal) or 1 (CAS NFA)

The valid values are:

[0] None = (Default) IP.
[1] Blind = PBX blind transfer:
E1/T1 CAS: When a SIP REFER message is received, the device performs a blind transfer, by performing a CAS wink, waiting a user-defined time (configured by the WaitForDialTime parameter), dialing the Refer-To number, and then releasing the call. The PBX performs the transfer internally.
[2] Semi Supervised = PBX semi-supervised transfer:
E1/T1 CAS: The device performs a CAS wink, waits a user-defined time (configured by the WaitForDialTime parameter), and then dials the Refer-To number. If during the user-defined interval set by the WaitForBusyTime parameter, no busy or reorder tones are detected, the device completes the call transfer by releasing the line. If during this interval, the device detects these tones, the transfer operation is cancelled, the device sends a SIP NOTIFY message with a failure reason (e.g., 486 if a busy tone is detected), and then generates an additional wink toward the CAS line to restore connection with the original call.
[3] Supervised = PBX Supervised transfer:
E1/T1 CAS: The device performs a supervised transfer to the PBX. The device performs a CAS wink, waits a user-defined time (configured by the WaitForDialTime parameter), and then dials the Refer-To number. The device completes the call transfer by releasing the line only after detection of the transferred party answer. To enable answer supervision, you also need to do the following:
1) Enable voice detection (i.e., set the EnableVoiceDetection parameter to 1).
2) Set the EnableDSPIPMDetectors parameter to 1.
3) Install the IPMDetector DSP option Feature License Key.

SMDI Parameters

'Enable SMDI'

configure voip > gateway voice-mail-setting > enable-smdi

[SMDI]

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

[0] Disable = (Default) Normal serial
[1] Enable (Bellcore)
[2] Ericsson MD-110
[3] NEC (ICS)

Note:

For the parameter to take effect, a device restart is required.
When the RS-232 connection is used for SMDI messages (Serial SMDI), it cannot be used for other applications, for example, to access the Command Line Interface (CLI).

'SMDI Timeout'

configure voip > gateway voice-mail-setting > smdi-timeout-[msec]

[SMDITimeOut]

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.

Message Waiting Indication (MWI) Parameters

'MWI Off Digit Pattern'

configure voip > gateway voice-mail-setting > mwi-off-dig-ptrn

[MWIOffCode]

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.

'MWI On Digit Pattern'

configure voip > gateway voice-mail-setting > mwi-on-dig-ptrn

[MWIOnCode]

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.

'MWI Suffix Pattern'

configure voip > gateway voice-mail-setting > mwi-suffix-pattern

[MWISuffixCode]

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.

'MWI Source Number'

configure voip > gateway voice-mail-setting > mwi-source-number

[MWISourceNumber]

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.

configure voip > gateway dtmf-supp-service supp-service-settings > mwi-subs-ipgrpid

[MWISubscribeIPGroupID]

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.

Notification IP Group ID

configure voip > gateway digital settings > notification-ip-group-id

[NotificationIPGroupID]

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

Note:

This is used for MWI Interrogation. For more information on the interworking of QSIG MWI to IP, see Message Waiting Indication.
To define the handling method of MWI Interrogation messages, use the 'MWI Interrogation Type' parameter in the Trunk Group Settings table (see Configuring Trunk Group Settings).

configure voip > gateway dtmf-supp-service supp-service-settings > mwi-qsig-party-num

[MWIQsigMsgCentreldIDPartyNumber]

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.
