Chapter 1 Networking in Cisco Unity
Voice Connector
Location, messages are decrypted by the Voice Connector before they are sent by Exchange over the Internet or any TCP/IP network via SMTP. (Messages to regular Internet subscribers are sent directly by the Exchange server and cannot be decrypted and therefore cannot be played by the recipient.)
Optionally, you can also create “external” subscribers (that is, AMIS, Bridge, and/or VPIM subscribers). The messages for external subscribers are stored externally to the Cisco Unity voice message store. When creating an external subscriber, you specify a delivery location that the external subscriber is associated with so that Cisco Unity has the information it needs to send messages to them.
Voice Connector
The Cisco Unity Voice Connector for Exchange is a Cisco Unity networking component that enables messaging between Cisco Unity servers and other voice messaging systems.
The Voice Connector for Exchange 2000 can be used when your network consists only of Exchange 2000 or Exchange 2003 servers, or a mixture of Exchange 2000, Exchange 2003, and Exchange 2007 servers.
Caution The Voice Connector for Exchange 2000 can be installed on an Exchange 2000 server or an Exchange 2003 server, but it cannot be installed on an Exchange 2007 server.
The Voice Connector performs the following functions:
•AMIS
UAmis_<Servername> mailbox for outgoing analog delivery. Incoming AMIS voice messages received by the Cisco Unity AMIS bridgehead are routed to the Voice Connector for processing.
•Bridge
•VPIM
–Cisco Unity servers that access separate directories
–Cisco Unity with Domino systems and Cisco Unity with Exchange systems
–Cisco Unity and Cisco Unity Express
Note that the Voice Connector is not needed with Digital Networking because the Cisco Unity servers access the same directory.
The Voice Connector ships with Cisco Unity and is available on the Cisco Unity Voice Connector for Exchange Software Download page, at
Active Directory Schema Extensions
A small subset of Cisco Unity data is stored in Active Directory. Therefore, before installing Cisco Unity, the Active Directory schema must be extended. In addition to the schema extensions required before installing Cisco Unity, the Active Directory schema must be extended before setting up the following:
