Question : CallManager vs Sip proxy server

Hi,

I`m little confuse: what difference between Cisco Call manager and Cisco SIP proxy server?
Thanks in advance.

Answer : CallManager vs Sip proxy server

Cisco CallManager is the software-based call-processing component of the Cisco IP telephony solution. The software extends enterprise telephony features and functions to packet telephony network devices such as IP phones, media processing devices, voice-over-IP (VoIP) gateways, and multimedia applications. Additional data, voice, and video services such as unified messaging, multimedia videoconferencing, collaborative contact centers, and interactive multimedia response systems interact with the IP telephony solution through Cisco CallManager's open telephony application programming interface (API). Cisco CallManager is installed on the Cisco Media Convergence Server (MCS) 7800 series and the Cisco Integrated Communication System (ICS) 7750.

==============================================================
The Cisco SIP Proxy Server is a call control software package that enables service providers to build scalable, reliable Voice over IP networks today. Based on the Session Initiation Protocol (SIP), the Cisco SIP Proxy provides a full array of call routing capabilities to maximize network performance in both small and large packet voice networks.
