This chapter provided an overview of Cisco Unity Connection software and the necessary elements to consider when designing a voice-messaging system. You learned how to
- Determine the specific server sizing based on users, codec, ports, and client applications.
- Understand the basics of how Cisco Unity Connections version 8.x handles codecs and transcoding for voice messaging.
- Understand the differences between IMAP Idle and IMAP non-Idle and how the amount of users is affected in the design considerations.
- Describe how high-availability and redundancy is accomplished using the active-active cluster-pair model with Cisco Unity Connection version 8.x servers.
- Determine the server sizing based on the physical or virtual platform overlays and the amount of ports and users supported.
- Understand intrasite and intersite networking using Cisco Unity Connection and describe the protocols, advantages, and limitations.
- Describe VPIM networking and how it is used with Cisco Unity Connection and other Cisco voice-messaging products.
- Determine the specific technology requirements based on the voice-messaging system and assemble information collected in the planning phase to create a preliminary design based on the users, location, and geography of the organization.
