1. Process for monitoring the quality of service of a communication through a communication network, said process being executed in a end-user terminal and comprising the steps of:
establishing a session between a first end-user terminal and a second end-user terminal via a signaling plane using a session initiation protocol;
monitoring the quality of service of the communication during said session;
transmitting information representative of said quality of service during said session using said signaling plane, wherein the QoS information is transmitted within the header of a session initiation protocol message, so that all parties share the same information, wherein said information representative of said quality of service comprises signaling parameters and media transmission quality parameters, said signaling parameters including a parameter which is representative of the time between one invite and the resulting ringing signal for this invite.
