MWI

Depending on the PBX and the respective telephone (e.g. feature-added telephone), the incoming of UMS-messages (faxes, voice mails, SMS) can be signaled at the telephone of the user. This is the so-called feature MWI (Message Waiting Indication).

For switching on hte indication at the telephone, the ixi-UMS Kernel transmits a corresponding signal to the PBX. At last, the MWI is switched on by the PBX.

For switching off the indication at the telephone, a so-called "Alert-Message" is sent to the ixi-UMS Kernel by the mail client, by ixi-UMS Notifier Expreß or by the Mobile Notifier. The ixi-UMS Kernel passes the information on to the PBX. By doing so the PBX is caused to delete the MWI at the respective user's telephone. For information about the addressing and the format of these Alert-Message, please have alook at the HowTo . You can also get information about the requirements there.
