Hi all,
From some days ago we are seeing a problem of jitter increased jitter in some telepresence sessions that go through a multipoint switch. We reviewed the network and there aren't problems.
What we have found is that in some multipoint sessions, not all the rooms are negotiating with the QoS traffic marking DSCP AF41, but some rooms remain in AF12 during the call and just those rooms (in AF12) the people on the meeting are complaining of poor quality in the video, picture freeze, video cuts.
Can be the problem with the multipoint switch that not all rooms to negotiate AF41? Is it possible to increase the jitter for this reason?
