Abstract
A system and method for handling multimedia conference calls in a telecommunication network. To determine the capabilities of the other terminals in a group, a first terminal sends a query message to a group server. The group server sends further query messages to the other terminals and collects their responses containing their capabilities. The group server analyzes the capabilities to determine a common set of capabilities. The group server then sends the common set of capabilities in a response to the first terminal.
