Applied multiprotocol routing in IP telephony

摘要

The aim of the project was to create a multiprotocolsystem using SIP, H.323 and MGCP standards,which would ensure routing to various types of VoIPnetworks. The priority was to provide multi-protocolsupport to SIP and H.323 signalling and the support of therouting using the ENUM standard which has recentlypassed from the trial phase into full operation in the CzechRepublic. The document describes the system's architectureand the components used. It also briefly describes ENUM.
