5. Configuring Your System
Select Required to have H.235 calls secured between VidyoGateway and Legacy

devices at all times (regardless of Legacy endpoint support for encryption for the
protocol).
If Legacy endpoint calls are set to Required, your VidyoPortal must be running the
Vidyo encryption software option for a successful connection.
f. In the Video Codec drop-down, select Voice Only, H.264, H.263, H.264/H.263 highest
priority, or H263/H.264 highest priority as your video codec.
When you select Voice Only, the Bandwidth field becomes read-only and the
Resolution and FPS drop-downs disappear from the
g. In the Audio Codec drop-down, select G.711, G.722, G.711/G.722, or G.722/G.711 as
your audio codec.
h. In the Resolution drop-down, select CIF, SD, HD-720P, or FHD-1080P as your
resolution.
The setting determines the maximum resolution used for your service.
To determine the maximum number of concurrent calls of the same type and resolution
for your VidyoGateway server, see
Type. For example, you should select HD1080 only if you have a VidyoGateway XL and
for not more than two concurrent calls. (Not applicable for audio-only calls.)
When you select a Resolution value, the Bandwidth is changed accordingly in the

following manner: CIF = 384 kbps, SD = 768 kbps, HD-720P = 1600 kbps, and
FHD-1080P = 3072 kbps.
If you select the Voice Only option as your Video Codec, the Resolution is fixed at

64 kbps.
Although you must select a Resolution when you configure your service, the system

dynamically negotiates both the bandwidth and resolution according to the Legacy
device. VidyoGateway does not negotiate higher than the configured resolution.
i. In the FPS drop-down, select 5, 10, 15, 20, 25, or 30 as your frames per second.
j. In the Bandwidth (kbps) field, enter a numeric value (in kbps) for the maximum
bandwidth available for your service.
The number that displays in this field is based on the Resolution selected in the

following manner: 384 kbps = CIF, 768 kbps = SD, 1600 kbps = HD-720P, and
3072 kbps = FHD 1080P.
If you select the Voice Only option as your Video Codec, the Resolution is fixed at

64 kbps.
k. In the Call Type drop-down, select P2P (Point to Point, from Legacy only) or
Conference (to Legacy) as your audio codec.
This field only displays when From Legacy is selected in the Direction field. If To
Legacy is selected as the direction, the field is fixed as Conference/P2P.
l. In the Mode drop-down, select from the following:
