Cisco Unity vs. Microsoft Exchange Unified Messaging

Cisco Unity vs. Microsoft Exchange Unified Messaging

A fundamental difference between Cisco Unity and Exchange Unified Messaging is Cisco’s ability to offer end-to-end support for all system components. If a customer needs a gateway for legacy PBX integration, for example, Cisco will OEM this product and the Cisco TAC will support related issues. The customer only has to deal with one vendor for problem resolution.

In contrast, Microsoft uses Dialogic and Audiocodes gateways for these types of integrations, but does not support the gateways. For message waiting indication, Microsoft suggests a MWI application from Geomant but also does not support this solution. As such, a customer that is having an issue with something as simple as an MWI lamp lighting may have to deal with three vendors: Microsoft, Dialogic/Audiocodes, and Geomant. In contrast, Cisco stands behind the entire Cisco Unity solution.
