Voice Servers are made to provide all common voice services used in telephone systems. They are designed for continuous unattended operation. All messages and voice prompts are stored digitally on the internal hard disk. A call attendant answers calls and offers services. Possible services are to offer a selection of internal numbers to connect to, to offer a selection of languages or to just provide spoken information.
Announcers are designed to answer to incoming calls and place callers in a waiting queue if needed. A spoken message could tell the caller who he has reached, how many people are waiting in the queue and what the estimated waiting time is. An announcer does not offer menu’s, and, unlike a voice server, it doesn’t take voice mail. It’s main function is to answer to incoming telephone calls.
