Field Name Description
If you set Use QoS to Yes, you provide different priority to different data
stream, or guarantee a certain level of performance to a data stream. In
particular, you may choose between Precedence/TOS and Differentiated
Service.
Quality of service Choose to set the priorities by entering a custom numeric value, or enter a
relative priority ranking. These are the two methods used by network
components like routers or switches to implement their QoS settings:
• Select DiffServe, short for Differentiated Service, if your network
components set a custom priority value for each type of data.
• Choose Precedence/TOS if your network components define QoS as a
precedence ranking and a designated type of service (TOS) for each type
of data.
Audio, Video,
Data, Signal
Set the value for each type of data, according to your choice in the Quality of
Service field.
DiffServe Enter the custom priority value, also known as differentiated service or
DiffServe, if QoS is implemented like this in your other network components.
The values must be identical throughout your network, and for all remote
endpoints connecting in videoconferences.
TOS and
Precedence
Enter the type of service, alongside the precedence (priority ranking) of each
type of data, identical to the settings of all other network components, and
any remote endpoints connecting in a videoconference.

About this task
As part of H.323 network setup, the Avaya Scopia
®
XT Series must be registered to a gatekeeper,
like Avaya Scopia
®
ECS Gatekeeper.
A gatekeeper routes audio and video H.323 calls by resolving dial strings (H.323 alias or URI) into
the IP address of an endpoint, and handles the initial connection of calls. For example, you can dial
1234 or joesmith and the gatekeeper routes the call correctly.
To do this, the gatekeeper must register all endpoints to maintain the mapping list of aliases and
endpoints to successfully route calls. It also registers gateways like an ISDN gateway or Scopia
®
Video Gateway, so it can route calls to a non-H.323 device. Registration with a gatekeeper may
happen every time the endpoint is switched on, or after a set period.
You can also secure your connection with the gatekeeper by enabling authentication. You can enter
a special username and password in both the endpoint and the gatekeeper as a shared secret,
which is used to authenticate the identities of the gatekeeper and endpoint.
