The invention relates to a method for managing at least one communication pathway between a first router (30) and a second router (130), being characterised in that it comprises the following steps: establishing a session (40) between a terminal (10) connected to the first router (30) and a remote piece of equipment (70) connected to the second router (130); analysing at least one characteristic of the session (40) in order to determine whether said session (40) is collaborative and if this is the case: receiving at least one signalling message containing at least one piece of information relating to a characteristic of said session (40); determining parameters of the connection between said routers (30, 130) depending on the at least one obtained piece of information; modifying the at least one communication pathway (80) between said routers (30, 130), depending on the determined connection parameters; and transmitting the data of said session (40) over said modified communication pathway (80).
