MWI - Signaling

Basically, the MWI-service (address type "Alert") is used for the signaling of new messages by indication of a signal at the user's telephone. This is normally the light up of a signal lamp or the indication of a message at the telephone display.

When the signaling is not transmitted to the PBX e.g. via a modem, the following protocol properties are required, depending on the protocol:

This feature depends on which PBX is used. Further information about the configuration are listed at "Hardware - Alert".

At this configuration, the Hicom-service "Associated Dialing" is used, by which an info text at the telephone is switched on and off.

In the HiPath, code numbers have to be defined for "MWI on" and "MWI off". The digits 0 - 9 are valid as code numbers in combination with the ixi-UMS Kernel .

In the ixi-UMS Kernel Configuration, 7568 is deposited for "MWI off" and 7668 for "MWI on" by default.

In the ixi-UMS Kernel Configuration at Hardware - Alert "HiPath 3000 DSS1 ISDN Dial" has to be selected. In the Configuration, the code numbers might have to be changed and the OffInsertDest=0 (Default) has to be set.

In order to be able to make use of MWI at a PP connection, this has to be configured in the HiPath on ISO Q-SIG (Master direct).

That way, the first text deposited in the PBX is indicated always and the MWI is set.

An ISDN-board that supports the protocol Q-SIG has to be applied.

%Firma% recommends Dialogic (Eicon) Server boards, in whose configuration manager, the protocol "Q-SIG - HiPath 3000" has to be set.

In the ixi-UMS Kernel Configuration at Hardware - Alert "HiPath 3000 Qsig MWI" nothing has to be changed by default.

In order to realize MWI at a HiPath 4000, the connection has to be configured on Q-SIG (ECMA V2).

The MWI at the telephone is switched on and off.

An ISDN-board that supports the protocol Q-SIG has to be applied.

%Firma% recommends Dialogic (Eicon) Server boards, in whose configuration manager, the protocol "Q-SIG - HiPath 4000" has to be set.

In the ixi-UMS Kernel Configuration at Hardware - Alert "HiPath 4000 Qsig MWI", the "Service Access Number" has to be entered.

In the PBX, "Voice Mail" has to be enabled and a "Voice Mail Number" has to be deposited.

The XCAPI has to be set to "SIP-Notify" at Service Criteria - MWI under MWI-Protocol.

In the ixi-UMS Kernel Configuration at Hardware - Alert "General VoIP (XCAPI)" has to be chosen. Changes in the configuration are not required basically.

Required is the configuration of the MWI On/Off numbers in the Cisco CallManager.

In the XCAPI-configuration, the method ‚Cisco CallManager compatible' has to be selected at Supplementary Services - MWI.

At Supplementary Services - MWI - Cisco CallManager compatible, the phone numbers must be entered, which are used for ‚MWI on' and ‚MWI off' at the CallManager.

In the ixi-UMS Kernel Configuration at Hardware - Alert "General VoIP (XCAPI)"  has to be chosen. Changes in the configuration are not required basically.

From Version 5.01 on, the PBX's support the MWI-signaling according to H450.7 with the signaling via H.323.

The XCAPI must be set to "H.450.7" at Supplementary Services - MWI under MWI-Protocol.

In the ixi-UMS Kernel Configuration at Hardware - Alert "General VoIP (XCAPI)" has to be chosen. Changes in the configuration are not required basically.

In order to be able to send MWI to an Alcatel 4400 or OmniPCX Enterprise, the PBX has to be connected via Q-SIG. Moreover, ABC-F for QSIG GF has to be enabled.

An ISDN-board has to be applied, which supports the Q-SIG protocol and MWI on the basis of ABC-F.

estos GmbH recommends Dialogic (Eicon) Server boards, in whose configuration manager, the protocol "Q-SIG - Alcatel 4400...." has to be set.

In the ixi-UMS Kernel Configuration at Hardware - Alert "Alcatel QXE Qsig MWI" , the configuration has to be adjusted.

Please contact the person in charge of your PBX in order to get more detailed information about requirements and options concerning MWI at your PBX (configuration "Q-SIG and DSS1")

In the PBX, the needed digits are entered by default. Only if these have been changed, the digits at "OnPre" and OffPre" in the configuration must be changed.

Please take into account, that always the modem extension is displayed on the phone. In order enable a callback to the ixi-UMS Kernel number,

1) Route by Redirection must be used

2) the modem must be forwarded to the Route-by-Redir number.

For further information and configuration examples, please refer to the ixi-UMS Kernel Configuration.
