Descriptions

 

The Voice Mail System (VMS) is one of the value added peripheral of UltraWAVE system. It provides voice mail to the calling party when the called party is busy, no answer, not reachable or switched off. When a new voice message reaches, the VMS notifies the host by a short message. Subscribers can receive and retrieve their messages and maintain their mailboxes (set greetings, language and password) at any time from anywhere.

 

The VMS can be either deployed as part of the UltraWAVE system, or used as a standalone system. In an UltraWAVE system the VMS connects to the MSC. It also functions along with SMSC to provide message indications. Each VMS can also be configured to provide a multi-language announcement service. A single VMS supports 10k subscribers. The UltraWAVE system may deploy up to ten VMS to support 100k voice mail subscribers.
