Cisco E3CE-CCCSP-5CPS Unified SIP Proxy 5 CPS

Provide a defined 5 calls-per-second capacity tier for Cisco Unified SIP Proxy signaling in a collaboration environment. SIP proxies handle Session Initiation Protocol signaling rather than the voice media stream itself, making signaling capacity an important sizing measure for call setup activity, routing decisions, and SIP-based interconnection workflows. Cisco Unified SIP Proxy fits deployments where SIP signaling must be directed between voice systems, service-provider connections, session-border infrastructure, or other collaboration components. Administrators can use a calls-per-second figure to align proxy capacity with expected busy-hour call setup rates rather than sizing only around the number of registered endpoints or total users. E3CE-CCCSP-5CPS identifies the EA3.0 Cisco Unified SIP Proxy offering with a 5 calls-per-second capacity. That capacity designation distinguishes it from higher-capacity selections in the same service area and should be matched to the anticipated signaling load, including inbound, outbound, transfer, and rerouting activity that may occur during peak call periods.
