Acting as a Message Center
The Octel Overture 200/300 can also be set up to answer forwarded calls and act as a message center. For
example, a company with a service providerCentrex service already has a means of getting calls directly
to an extension. When the extension is busy or does not answer, the extension can be forwarded to an
Octel Overture 200/300 hunt group to take a message. Ports receiving forwarded calls are configured in
CX mode. The Octel Overture 200/300 does not attempt to call the extension number entered by the
caller but immediately goes to that extension’s mailbox and offers to take a message.
The attendant may also extend callers to a port to allow them to leave a voice message. This port is
configured as MX mode. As with CX mode, it does not call the extension number entered but goes to that
extension’s mailbox and offers to take a message.
Using the DID/E&M Trunk Interface
DID and E&M trunks are wired through the DID/E&M Trunk Interface so that it can monitor the
progress of those calls. If appropriate, the interface diverts the call to the Octel Overture 200/300 for call
coverage. The DID/E&M Trunk Interface and the Octel Overture 200/300 communicate via an RS-232C
serial link. Ports receiving calls from the DID/E&M Trunk Interface can be in any mode. The Octel
Overture 200/300 handles the call based upon information sent by the DID/E&M Trunk Interface module.
Refer to the DID/E&M Trunk Interface Installation and Maintenance manual for more information about
how the DID/E&M Trunk Interface works.
