Message Addressing Options

Table 1-1	Networking Options (continued)
Networking Option		Description
Internet Subscribers		Allows messaging with individuals over the Internet or any TCP/IP network by using SMTP. The
		recipient receives the message as an e-mail with a WAV attachment. Internet subscribers can have
		local extensions, recorded voice names, and greetings, and be listed in the directory, but they do
		not have mailboxes in the local Exchange network. Messages are addressed to Internet subscribers
		as they are to regular subscribers, but the messages are sent to the e-mail address that you specify
		when creating the Internet subscriber account.
Trusted Internet		Trusted Internet subscribers are Internet subscribers that are trusted with decrypted secure
Subscribers		messages. Trusted Internet subscribers must be associated with a Trusted Internet Location. Secure
		messages to Trusted Internet subscribers are decrypted by the Cisco Unity Voice Connector for
		Microsoft Exchange before they are sent by the Exchange server. (Messages to regular Internet
		subscribers are sent directly by the Exchange server and cannot be decrypted and therefore cannot
		be played by the recipient.)
AMIS		Allows messaging with other voice messaging systems that support the Audio Messaging
		Interchange Specification analog (AMIS-a) protocol. In essence, the sending voice messaging
		system calls the receiving voice messaging system, there is an exchange of DTMF tones as defined
		by the protocol, the sending system plays the message, and the receiving system records it.
Bridge		Allows messaging between Cisco Unity and an Octel system on an Octel analog network by using
		the Cisco Unity Bridge. The Cisco Unity Bridge acts as a networking gateway between
		Cisco Unity and the Octel system, and allows the systems to exchange voice and fax messages.
		Messaging between Cisco Unity and the Bridge is done over the Internet or any TCP/IP network
		by using SMTP. Messaging between the Octel servers and the Bridge is done by using the Octel
		analog networking protocol. The Bridge must be installed on a separate and dedicated platform.
VPIM		Allows messaging with other voice messaging systems that support the Voice Profile for Internet
		Mail (VPIM) protocol. VPIM allows different voice messaging systems to exchange voice, text,
		and fax messages over the Internet or any TCP/IP network. VPIM is based on SMTP and the
		Multi-Purpose Internet Mail Extension (MIME) protocol. VPIM Networking can be used for
		messaging between Cisco Unity servers that access different directories, between Cisco Unity and
		Cisco Unity Express, and between Cisco Unity with Exchange and Cisco Unity with Domino
		systems.

Message Addressing Options

With AMIS, Bridge, and VPIM Networking, you can set up different addressing options, as follows:

•Blind Addressing—With blind addressing, Cisco Unity has the information it needs to send messages to the remote voice messaging system, even though the recipient mailbox number, text name, and recorded name are not in the directory.

•“External” Subscribers—You create AMIS, Bridge, and/or VPIM subscribers on the local Cisco Unity server to correspond to subscribers on the remote voice messaging system. These external subscribers (also referred to as “proxy users” or “remote subscribers”) can have local extensions, recorded voice names, and greetings, and can be listed in the directory. However, they do not have mailboxes in the local Exchange network. Messages are addressed to an external subscriber as they are to a regular subscriber, but the messages are sent to the applicable mailbox on the remote voice messaging system. External subscribers have corresponding Active Directory contacts.
