Advanced > QoS
Quality of Service offers a defi ned level of performance in a data communications system - for example the
ability to guarantee that voice traffi c is given priority over other network traffi c to ensure that conversations
are not disrupted by other network requirements. This means that should you be talking via the VoIP facility
and someone else in the house starts downloading a big fi le, the download won't disrupt the fl ow of voice
data.
