SIP and SCCP
Skinny Call Control Protocol
The Skinny Client Control Protocol is a proprietary network terminal control protocol originally developed by Selsius Systems, which was acquired by Cisco Systems in 1998. SCCP is a lightweight IP-based protocol for session signaling with Cisco Unified Communications Manager, formerly named CallManager. Examples of SCCP clients include the Cisco 7900 series of IP phones, Cisco IP Communicator …
Voice over IP
Voice over IP (VoIP) is a methodology and group of technologies for the delivery of voice communications and multimedia sessions over Internet Protocol (IP) networks, such as the Internet. Other terms commonly associated with VoIP are IP telephony, Internet telephony, broadband telephony, and broadband phone service.

What does SCCP stand for in Telecom?
The Signalling Connection Control Part (SCCP) is a network layer protocol that provides extended routing, flow control, segmentation, connection-orientation, and error correction facilities in Signaling System 7 telecommunications networks. SCCP relies on the services of MTP for basic routing and error detection.
What is Cisco SCCP used for?
The Skinny Client Control Protocol (SCCP), or Skinny, is a Cisco proprietary signaling protocol for VoIP devices. As a signaling protocol, it is used for registration of endpoints; call messages such as off-hook, on-hook, addressing (dial numbers); and controlling phone display.
What is MGCP and SCCP?
MGCP reliance on call agent becomes single point of failure in the event communication between voice gateway and call agent is broken. Skinny Client Control Protocol (SCCP) – This is Cisco proprietary protocol and it is used to control Cisco IP phones and other Cisco endpoint devices such as ATA 186/188.
What is Cisco SIP?
Cisco CallManager can act as both a server or client (a back-to-back user agent). SIP uses a request/response method to establish communications between various components in the network and to ultimately establish a call or session between two or more endpoints.
Does SCCP use RTP?
A SCCP client uses TCP/IP to communicate with one or more Call Manager applications in a network. It uses the Real-time Transport Protocol (RTP) over UDP for the traffic (real-time audio stream) with other Skinny clients or an H. 323 terminal.

What is the difference between h323 and MGCP?
H. 323 gateway interfaces support the NFAS (Non-Facility Associated Signaling) feature, while MGCP gateways do not. The NFAS feature allows one Q. 931 D channel in a PRI to carry voice signaling for up to 20 PRIs.
Is SIP UDP or TCP?
SIP can be carried by several transport layer protocols including Transmission Control Protocol (TCP), User Datagram Protocol (UDP), and Stream Control Transmission Protocol (SCTP). SIP clients typically use TCP or UDP on port numbers 5060 or 5061 for SIP traffic to servers and other endpoints.
What is SIP on router?

What is a SIP gateway?
A SIP VoIP gateway is a device that enables a user to place VoIP calls using session initiation protocol (SIP). SIP is a telephony technology developed as a fast, easy standard for delivering IP-based voice, data, and video communications.
