Echo channels

Learn about echo channels for testing.

Last updated 8 months ago
Vivox provides an echo channel capability. This is often used to perform a quick check to ensure that voice is working properly in a particular environment.
To join an echo channel, use the channel that is prefixed with "confctl-e-".
Note
If multiple users are in the same echo channel, then they cannot hear themselves or other users.
To implement an echo channel, ensure that the game selects an echo channel URI that is unique. Do this by using the 
vx_get_echo_channel_uri()
method with the user's ID as the channel name or by using 
vx_get_random_channel_uri()
.
Warning
Attention: You must initialize the Vivox SDK before you can use either of these methods.
