With lab trials, you are really getting a taste of how Cisco Unity fits into the customer environment. Preferably, the customer also gets some good exposure to how Cisco Unity will operate in their corporate environment, particularly if you are able to pilot Cisco Unity in the production environment. You may be able to use this opportunity to understand how to network Cisco Unity with other voice messaging systems, if required -- valuable information to help the Design and Implement phases go smoothly.
