9.1 Configuring Captions

During a conference, you can create a caption, and then overlay the caption on the video sent by the local site. The caption can be overlaid on the top, in the middle, or at the bottom of the video.

The terminal supports T.140 and non-T.140 captions. Table 9-1describes the differences between these two types of captions.
