Introduction to VPIM

VPIM Networking allows the exchange of voice, fax, and text messages between different voice

messaging systems over the Internet or any TCP/IP network. VPIM is an industry-standard protocol

based on the Simple Mail Transfer Protocol (SMTP) and the Multi-Purpose Internet Mail Extension

(MIME) protocol.

VPIM enables organizations to link different voice messaging systems and to provide seamless voice

message sending, receiving, forwarding, and replying between these systems. An organization can

exchange messages over a TCP/IP-based intranet, or over the Internet, or a combination of the two. In

simplified terms, voice messages are exchanged between the systems like regular e-mail.

Network

VPIM Networking also enables messaging between Cisco Unity servers that access different directories,

specifically when the Cisco Unity servers are in different Active Directory forests. (When the

Cisco Unity servers are in the same Active Directory forest, Digital Networking is the solution to use

rather than VPIM Networking.)
