Abstract
MGCP ia standard protocol by IFTF, which is designed to facilitate inter-working with other protocols. Since the nature of protocol, it can be known as a proper solution to integrate heterogeneous networks consisted of various protocols and systems. In this paper MGCP is used for controlling VoIP gateways from external call control elements(MGCs) and introduces a method to improve interoperability for various MGC in a gateway based on MGCP. It presents implementation issues to provide the interoperability for MGC dependent parts such as call flows of message encoding, and a system architecture to resolve the issues.
