  • Establishing a call in a packet-based communications network
    Publication number: 20030233471
    Abstract: In order for a voice call or other communication session to be provided between entities in two different address domains, at least one of which is private, then a media proxy has previously been used to forward media packets. The present invention provides a way in which such a media proxy can be eliminated from a call flow after the initial stages of the call. This is achieved in the case that a network address translator involved in the call has a particular characteristic, such as being a cone network address translator.
