Method and network node for monitoring a quality of media transfer in a SIP based VoIP communications network comprising a first and second network node. The method includes the step of collecting, by the first network node, information representative of the quality of media transfer on the user plane, such as information included in one or more RTCP messages related to that media transfer, and including, by the first network node, in a SIP message said information representative of the quality of media transfer on the user plane. The method further includes transmitting the SIP message from the first network node to the second network node, and storing in a repository associated with the second network node the information representative of the quality of media transfer on the user plane. |
