CME_AMPreso_0705 Cisco Public Cisco Unified CallManager with SRST Pros/Cons Pros All employees in the organization have access to all features all the time Centralized or distributed Voicemail, Applications and DSP Resources Ease of management – only Cisco Unified CallManager needs ongoing changes. SRST is a “set it and forget it” deployment as the network takes care of itself Lower cost solution vs. deploying Cisco Unified CallManager Cluster at remote sites Transparent use of PSTN in SRST mode Cons SRST provides most of the commonly used features during a WAN outage to ensure business continuity Each SRST router needs initial configuration SRST router is limited to 720 phones and 960 extensions. Deployments larger than this number need to use multiple SRST routers and a Gatekeeper
