Cisco Unified Communications Manager Express
Cisco Unified Communications Manager Express (CME) is a feature-rich entry-level IP telephony
solution that is integrated directly into Cisco IOS software. Cisco Unified CME allows small business
customers and autonomous small enterprise branch offices to deploy voice, data, and IP telephony on a
single platform for small offices, thereby streamlining operations and lowering network costs.
Cisco Unified CME is ideal for customers who have data connectivity requirements and also have a need
for a telephony solution in the same office. Whether offered through a service provider's managed
services offering or purchased directly by a corporation, Cisco Unified CME offers most of the core
telephony features required in the small office, and also many advanced features not available with
traditional telephony solutions. The ability to deliver IP telephony and data routing by using a single
converged solution allows customers to optimize their operations and maintenance costs, resulting in a
very cost-effective solution that meets office needs.
