Video communication

T.Flex supports the following types of video communication:

  • One-to-one:
    • Video call
    • PTV (push to video) call
  • One-to-many:
    • Live video streaming
  • Many-to-many:
    • Multi PTV call
PTT hold timeout specifics:

Administrative configuration may define a PTT hold timeout for your user account, where you are allowed to hold the floor for no longer than a specified time and PTT is automatically released for you when the time limit is hit. This feature works in some situations but not in others – it is applicable where there is a PTT queue (floor control).
In particular, the timeout works for PTV calls but not for video calls.

One-to-one video communication

Video call

Users can exchange video calls in the TASSTA system. During a video call, each of the participants can change the speaker of the output sound, turn on and off the microphone and video camera, and switch between the front and rear camera view.

Note:

Make sure that you have a stable Internet connection when placing or receiving video calls. The quality of a video call depends on the contact with the weakest connection.

To make a video call

  1. Go to the user list by selecting it in the navigation drawer.
  2. Tap the user you need and then tap the video call icon. The available action icons are above the user list interface when a user is selected.
  3. Wait for the other user to accept your call, and then use the PTT button to start.
Receiving a video call:

When someone video calls you, you see an INCOMING VIDEO CALL screen, where you can accept or decline the call.

PTV call

This is a video call that does not require confirmation from the receiving party. A PTV call is declined if the receiving party is already in a call.

To make a PTV call

  1. Go to the user list by selecting it in the navigation drawer.
  2. Tap the user you need and then tap the PTV call icon. The available action icons are above the user list interface when a user is selected.

One-to-many video communication

Live video streaming

Video streaming can be the optimal way to report on something or make a quick presentation. You can stream live to one or more users of your choice at once.

To make a video stream

  1. Go to the user list by selecting it in the navigation drawer.
  2. Tap the Invite users to video stream icon.
  3. In the view that opens, select the users you need, and tap the same icon again.

Each of the invited users gets a notification about the start of your stream, and the stream's dynamic channel becomes available to them. They can join the channel at their convenience; this opens a video player showing the stream.

Viewing a live stream

In the stream player view, you have the following controls:

  • A button that hides the stream
  • A button that shows how many streams you are invited to and lets you switch streams
  • An indicator that shows how many users are viewing this stream

During the stream, you can use the PTT button to claim the floor and talk, as in a group call.

Many-to-many video communication

Multi PTV call

This is a PTV call with more than two participants.

To make a multi PTV call

  1. Go to the user list by selecting it in the navigation drawer.
  2. Tap the PTV call icon in the top bar and proceed to the user selection screen.
  3. Select the users you need and tap the PTV call icon again.
