A Multimedia Service Broker (MSB) 1 supplies multimedia content to end users 4 based on user identity and preferences, content format and security policies via a Session Initiation Protocol (SIP) interface and an Application Programming Interface (API) 2, which receives messages in different protocols from various network points (eg. VOIP apps) and converts them to a service query request in a common format. A SIP Servlet container enables the generation of SIP protocol requests, while the API can be used by non SIP Servlet compliant entities, and other protocols (eg. Skype) may be supported by a pluggable protocol adapter. The converted service requests are acted on by a Service Bundle Intelligence Container (SIC) 3 whose decisions are based on defined rules and policies.
