An additional session is established for voice over internet protocol communication between a pair of endpoints in a network, wherein a current session is already established between the endpoints and is currently used for data packet communication between endpoints. Qualities of each of the sessions for voice over internet protocol communication are assessed and compared, and the endpoints signaled to select the session having the higher assessed quality as a current session for further data packet communication between the endpoints, and to remove the lower quality session from use as a session for the further data packet communication between the endpoints, or to use the lower quality session as a secondary session for data communication between the endpoints. More particularly, the assessed qualities of each of the current and additional sessions meet a basic requirement defined to provide voice over internet protocol data packet communication between the endpoints.
