Abstract
A method of controlling an establishment of a multimedia call between at least two communication equipments, a corresponding system, and a corresponding communication equipment comprise a set up of a bearer connection resulting in a creation of a data transmission channel between at least two communication equipments. A data stream is transmitted between the at least two communication equipments after the creation of the data transmission channel for maintaining synchronization of the data transmission channel. Predefined information elements are introduced in the data stream, wherein the predefined information elements indicate local protocol settings for the multimedia call. The predefined information elements are recognized from the data stream, and parameters of an application protocol used for the multimedia call are adjusted on the basis of the predefined information elements.
