Send camera

control to

other

participants

Specifies whether FECC or DTMF from this

participant may control a far end camera.

This setting combines with layout control via

FECC/DTMF to control the camera of the far

end and the layouts of the conference. This

setting overrides the global conference

setting for this endpoint.

■ Disabled: This participant will not be

allowed to control a far end camera

using either FECC or DTMF.

■ FECC only: This participant will be

only be allowed to control a far end

camera using FECC.

■ DTMF only: This participant will be

only be allowed to control a far end

camera using DTMF.

■ FECC with DTMF fallback: This

participant will be allowed to control a

far end camera using FECC. If FECC is

not available, this participant will be

able to use DTMF for camera control.

■ FECC and DTMF: This participant will

be allowed to control a far end camera

using either FECC or DTMF.

There are two control mechanisms, FECC and

DTMF, either (or both) of which can be used for

camera control or layout control. If one

mechanism is allowed for camera control but not

for layout control, then that mechanism only

controls the far end camera and does not affect

the layout. Similarly, if one mechanism is allowed

for layout control but not for camera control, then

it is not possible to control the camera with that

mechanism. In these cases, the endpoint can use

FECC or DTMF controls directly to change the

layout or adjust the far end camera.

When one control mechanism can control either

the layout or the far end camera, then that

mechanism will always control the layout until

"Zoom in" (FECC mechanism) or 1 (DTMF

mechanism) is pressed. The control mechanism

then switches over to control the camera.

Far-end camera control always applies to the

camera of the participant shown in the largest or

top left pane (when panes are the same size). If

you have no way to control the layout, then you

cannot focus on a participant to allow you to

adjust a particular camera.
