Abstract

In a method for setting up a communication link between a first telephony terminal (PA) and a second telephony terminal (PB) in a communication network which transports data packets, in particular on the Internet, with the aid of at least one signalling Server (SA, SB), in particular with the aid of an SIP Server, the first telephony terminal informs a first signalling Server that a call is intended to be made to the second telephony terminal. The first signalling Server which has been informed or a second signalling Server which has been informed by this first signalling Server recognizes that the call is intended to be made with a particular quality of Service and sets up a communication link between the first telephony terminal and the second telephony terminal, which link corresponds to this quality of Service.
