Outside Caller
PBX-1
Extn.
101
[Explanation]
A CO line call is answered by the AA service of the Unified Messaging system. The caller enters extension
number 201, so the call is transferred over the private network to extension 201.
If extension 201 does not answer, mailbox 201 will answer it and play the appropriate message.

101
[Explanation]
Extension 201 does not answer the CO line call, so the call is forwarded to the Unified Messaging system,
and answered by mailbox 201. If the outside caller leaves a message, the Unified Messaging system sends
a Message Waiting notification to the extension using Enhanced QSIG information over the private network.
