摘要： A method of operating a Session Controller is provided. The Session Controller communicates with a client (40) and comprises a signalling proxy (10) and a media proxy (20), the Session Controller being latched to a media plane address and port. The method comprises: detecting, at the signalling proxy, that the client is changing or has changed its IP address and/or port to a different address and/or port; instructing the media proxy to monitor for incoming media from the client of an address and/or port different from the address and/or port that the media proxy has been using previously as the address and/or port of the client; and if any media is received by the media proxy of such a different address and/or port, using said different address and/or port as destination address and/or port for media from the media proxy to the client. A corresponding Session Controller, and a signalling proxy and a media proxy for use in such a Session Controller are also disclosed.

摘要： Apparatus for resolving a local TEL Uniform Resource Identifier to a service Uniform Resource Identifier for routing a message over an IP-based communication system. The apparatus comprises first processing means (2) for constructing a domain name system query string incorporating digits of the TEL Uniform Resource Identifier and a Context Identifier associated with the TEL Uniform Resource Identifier, and second processing means (3) for performing a Domain Name System lookup using said domain name system query string and for receiving in response said service Uniform Resource Identifier
