The present invention relates to a system and a method for handling multi media conference calls in a telecommunication network. In order for a first terminal (111) in a group (110) to determine the capabilities of at least on other terminal (112-114) in the group (110), a query message can be sent to the other terminal (112-114). When using SIP (Session Initiation Protocol), the query is performed by the method of sending an OPTIONS message. A limit ation with this method is that each terminal (111) in the group needs to sen d a query to all the other terminals (112-114) in the group in order to dete rmine the capabilities of each other. The invention comprises a common serve r (100) which is adapted to collect information about the capabilities for t he terminals (112-114) in the group and to determine a common set of capabil ities which is sent to the first terminal (111).
