The Implementation of Residential Media Gateway in Interworking Between Megaco/H.248 and SIP

چکیده
As a IP telephony protocol, the SIP is gaining increasing popularity. There is yet POTS(Plain Old Telephone Service) line as the existing subscriber line. The Megaco/H.248 may be used for call between the POTS line and SIP. So, it is needed that method for interworking between Megaco/H.248 and SIP. In this paper, we propose the implementation of Residential Media Gateway Prototype in Interworking between Megaco/H.248 and SIP. We had designed and implemented MG prototype platforms for interworking between POTS line and IP network in interwkoring of Megaco/H.248 and SIP protocol. And, we had found that it is feasible in the real network.

OPNET Implementation of Megaco/H.248 Protocol
The best-known media gateway control protocols are currently Media Gateway Control Protocol (MGCP) and Megaco/H.248. MGCP, described as informational RFC 2705, has been widely deployed. Megaco/H.248 has evolved from MGCP. It is a single unified protocol that resulted from the cooperation between the Internet Engineering Task Force (IETF) and the International Telecommunication Union (ITU). Mega...

This article discusses technical issues related to delivery and control of IP multimedia services, such as videoconferencing, involving heterogeneous end terminals. In particular, it describes the design and implementation of an experimental system for interworking between IETF SIP (Session Initiation Protocol) and ISO MPEG-4 DMIF (Delivery Multimedia Integration Framework) session and call con...
متن کاملInterworking Between SIP/SDP and H.323
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). We describe how a signaling gateway can allow SIP user agents to call H.323 terminals and vice versa. Our solution addresses user registration, call sequence mapping and session description. We also describe and compare variou...
