Configuring QoS settings
To configure Quality of Service (QoS) on the ISDN gateway for audio and video, go to
Network > QoS
.
QoS is a term that refers to a network's ability to customize the treatment of specific classes of data. For
example, QoS can be used to prioritize audio transmissions and video transmissions over HTTP traffic.
These settings affect all audio and video packets to H.323 endpoints. All other packets are sent with a
QoS of 0.
The ISDN gateway allows you to set six bits that can be interpreted by networks as either Type of Service
(ToS) or Differentiated Services (DiffServ).
Note:
Do not alter the QoS settings unless you need to do so.
To configure the QoS settings you need to enter a six bit binary value.
Further information about QoS, including values for ToS and DiffServ, can be found in the following
RFCs, available on the Internet Engineering Task Force web site
www.ietf.org
:
RFC 791
RFC 2474
RFC 2597
RFC 3246
