Abstract
This invention relates to a method for enhancing the quality information of a VoIP session by deducting information from received ICMP messages, in addition to quality information already collected from media streams and/or signaling streams of the same VoIP session. ICMP messages passing on the network link are monitored and correlated with an existing and ongoing VoIP session, i.e. media stream, already monitored by a media plane monitoring unit. A data record for the media stream(s) is expanded with information from the ICMP messages, thus giving a better and more complete quality feedback of the media stream reception at the two communication endpoints.
