The Cisco 3845 meets the IP Communications needs of midsize to large enterprise branch offices, while delivering industry-leading security within a single routing platform. By embedding voice services inside the router, Cisco provides customers with maximum deployment flexibility, plus higher densities for stations, trunks, and conferencing.
The Cisco 3845 router offers the award-winning Cisco IP Telephony solution, Cisco CallManager Express (CME), as an optional feature set embedded within Cisco IOS Software. This solution is ideal for customers who want to decrease costs and complexity by converging voice and data networks. By adding a Cisco Unity Express advanced integration module (AIM) or network module to this solution, small offices and branch offices can take advantage of a complete, all-in-one data, voice-processing, voice-mail, and auto-attendant system. For larger, centralized IP Communications deployments, customers can deploy Survivable Remote Site Telephony (SRST) in Cisco 3845 router with a central Cisco CallManager for highly scalable, highly available enterprise IP Communications. SRST is an important component of the Cisco end-to-end IP telephony offering, providing feature-rich call-processing redundancy, while taking advantage of the existing infrastructure at the branch office.
