A method and a resource broker are provided to control a conference session. The resource broker receives, from a conference controller, a message requesting to set up a conference communication for a participant. The message indicates whether a terminal of the participant supports selective forwarding. The resource broker verifies the availability of local selective forwarding and multipoint control resources. Based on the capabilities of the terminal and based on local resource availability, a reply is sent to the conference controller, indicating that the conference communication should be set up in selective forwarding or multipoint control mode, using local resources or resources of a network cloud. When a new participant is added or when a monitoring agent reports a change of availability of the local resources, the conference communication may be moved between the network cloud and the local resources, or change between selective forwarding and multipoint control modes.
