GATEWAY
RESOURCES FOR
CALLS
The Resources section is available in PRI Gateways only.
In the Resources section of the Settings tab, you can reserve Gateway resources
for T.120 enabled calls and for audio transcoded video calls. This section also
displays the total number of calls that the Gateway supports at specified
bandwidths.
The Gateway provides full end-to-end T.120 data collaboration sessions,
provided that all terminals support the T.120 standard in their conferencing
applications. In video calls with data transfer, the Gateway accepts whatever
bandwidth the ISDN connection defines for the data and dynamically adjusts the
outgoing bandwidth used for data by using the MLP, HMLP and VarMLP
formats.
You can also configure the Gateway to prioritize the transcoding, giving
preference to a particular codec that is applied to calls, thus optimizing the
resource allocation utilized by each call.
The Gateway supports up to 30 video calls on two B channels. If transcoding or
T.120 capabilities are required, the Gateway has to reserve resources for these.
The Gateway can differentiate between those calls that support T.120 and those
that do not. When receiving calls, the Gateway can check whether you are
reserving resources for transcoding or for T.120 capabilities.
 Procedure
1 In the Gateway interface, on the sidebar, click Gateway (if not already
selected).
2 Click the Settings tab.
3 Click Resources.
4 In the Maximum number of T.120 calls field, enter the number of T.120
enabled calls that you want to reserve Gateway resources for. The
maximum number is 18.
5 In the Maximum number of video calls with audio transcoding field,
enter the number of audio transcoded video calls you want to reserve
Gateway resources for. The maximum number is 20.
Note The term audio transcoded video calls refers to the process whereby
an audio stream in a multimedia call is transcoded from one codec type to
another.
