The Cisco? SIP Proxy Server is a software application that provides call-routing services in an IP telephony network. Using the Cisco SIP Proxy Server, service providers and enterprises can create large-scale, highly reliable packet voice networks.


Cisco CSCP-Edge Proxy (CSCP-EP) provides the edge adaptation of SIP signaling for diverse access networks, enabling seamless interoperability between multiple access locations and core network services and resources. The CSCP-EP provides user authentication, signaling compression, QoS signaling for access networks, security, STUN for Network Address Translation (NAT)/Firewall traversal and other adaptation functions. The CSCP-EP maps to the Proxy CSCF (P-CSCF) in the 3GPP IMS specification.
