A Windows service is activated to control the Quality of Service. The
voice data (RTP) are then prioritized in the network according to IEEE
802.1p (DiffServ marking 'EF'). If you encounter problems such as
one-way communication (one party has trouble hearing another),
they may be due to QoS errors in the network (e.g. switch components
that do not handle 802.1p correctly). In this case, deactivate QoS for
the local network.
