SIP and H . 323 — interworking VoIP networks
نویسنده
چکیده
H.323 is currently the industry’s predominant standard for offering multimedia services over IP networks, although the session initiation protocol (SIP) continues to generate significant interest in the market-place for rendezvous-based real-time applications. With its greater maturity, H.323-based equipment continues to be deployed in operational networks. However, with the advent of SIP-based third generation mobile networks and the continued development of voice over cable TV networks based upon SIP, significant deployments of SIP-based networks are on the horizon. Interworking between SIP and H.323based equipment is of significant importance to BT and its Joint Venture partners. This paper highlights some of the issues surrounding protocol interworking between the H.323 and SIP protocol sets.

Patterns for VoIP Signaling Protocol Architectures
Voice over IP (VoIP) is an alternative to traditional circuit-switched telephony that allows human voice and video to travel over existing packet data networks along with traditional data packets. H.323 and SIP are the two standard protocols used today for signaling and call control in VoIP, and they are essential for providing total access and for supporting IP-based services. In order to prov...

Modelling and Verification of Interworking between SIP and H.323 Ligang Wang Various standards organizations have considered signaling for voice and video over IP from different approaches. There are currently two standards for signaling and control of Internet telephone calls, namely ITU-T Recommendation H.323 and the IETF Session Initiation Protocol (SIP). H.323 is an umbrella standard that p...
متن کاملComparison of Call Signalling Protocols for Ad-hoc Networks
The two major standards in the multimedia services over IP area are the protocol suites H.323 (ITU-T) and SIP (IETF).Both have emerged as competing protocol standards for the signaling and call control of IP telephony. SIP is designed with a broader scope, offering functions specifically designed to enable easy extensions; it should be the advantage for new potential services. H.323 is still th...
متن کاملSIP-H323: A Solution for Interworking Saving Existing Architecture
In the 3rd generation multimedia communication world and in the 3GPP standardization consortium, SIP protocol appears to be the preferred signaling protocol. However, the need to communicate with non-SIP based network, e.g. H.323 from ITU-U, is still a reality. The need can be satisfied with the introduction of network gateways (also named Inter-Working Function). One of the open issues about S...
متن کاملAn Integrated Call Agent of the Coveraged VoIP Network
The traditional circuit-switched telecommunication network and the packet-switched data network are converging to a single packet-switched network. One important application of the converged network is telephony communications, also referred to as VoIP (Voice over IP). Call signaling protocols, such as H.323, SIP and MGCP, have been developed to support VoIP communications. To enable devices us...
