Abstract: A method for intermediating a plurality of network operators and one or more developers is provided. The method includes the steps of: obtaining, by an obtaining unit, a requirement about a computer program required by each network operator; integrating, by an integration unit, mutually-related requirements among the obtained requirements into one requirement; generating, by a generation unit, information about the necessity for development of a computer program implementing the integrated requirement; and presenting, by a presentation unit, the one or more developers with the integrated requirement and the information about the necessity.

Abstract: The present invention relates to methods and arrangements for providing caller information to a SIP enabled client (320), e.g. an IPTV client, in a communication network (10). The SIP enabled client (320) is connected to a SIP communication client (310), e.g. a VoIP client, in a home network (300). When another SIP communication client (100) in the communication network (10) calls the VoIP client (310) the call is forwarded to the VoIP client and forked to a caller ID application server (200). As the IPTV client has registered for a subscription to caller information on communication destined to the VoIP client in the home network, it receives caller information of the SIP communication client (100) from the caller ID application server (200) if the VoIP client has enabled the caller information functionality.
