Standardizing call control in Voice over Internet applications: a MGCP approach

This paper will discuss a new approach to standardize call control in Voice over the Internet applications. Voice over the Internet applications are the latest commodities in the technology world and people with related expertise are working to make the system more efficient with respect to both the quality of service and the economic point of view. The major problem currently facing solution providers for Voice over the Internet applications is the lack of interoperability. That is the Voice over the Internet Protocol (VoIP) system of one provider is not compliant with that of another. The reason the providers need to be in compliance is that if more gateways are able to communicate with each other more connectivity is achieved. Greater connectivity, in turn, reduces the cost for the users. It is with interoperability in mind that people started the development of the Media Gateway Control Protocol (MGCP) where the ultimate goal is to make all products compatible. The Media Gateway Control Protocol is a messaging protocol that specifies the way in which a call agent and the gateways communicate with one another. The basic implementation of the MGCP protocol is composed of two modules the call agent, which is also known as the Gatekeeper and the gateway.
