During a call
Once a call has been set up, there are a number of actions that can be prompted in Movi, either as a
result of a user action or as an automated response to changing conditions.
Multiway initiation
Multiway is the ability for a user to join calls and seamlessly create a multi-participant conference. If
multiway is initiated by the user, the current call is put on hold (there has to be at least one other call
already on hold) and all the endpoints are redirected to a multi-conference system according to the
Multiway Participant URI
provisioning option.
Muting media streams
If the camera or microphone is muted, Movi allocates the bandwidth for the other media links to use. This
means that if the user does not have enough bandwidth for two video streams, it is possible to mute one
video stream and improve the quality of the other stream.
To prevent the unused link from being closed (for example by a firewall), Movi sends STUN keep alive
messages every 7 seconds.
Automatic bandwidth adaptation
In case of a Movi client sending or receiving bandwidth which exceeds the network capabilities, high
packet loss may occur and the user may experience poor call quality. Movi uses automatic bandwidth
adaptation mechanisms to tackle bandwidth issues.
Note:
Automatic adaptations take time. Configuring the client to fit the network and system capabilities
is always recommended.
Automatic CPU adaptation
Running Movi with the highest video quality on a less powerful computer might result in 100% CPU
usage and a poor call quality. Movi monitors the CPU usage of the computer.
If CPU usage exceeds 95% for 10 seconds or more:
n
if Movi is responsible for less than 90% of the CPU usage, it will display a warning asking the user to
close other applications.
n
if Movi is responsible for 90% or more of the CPU usage, it will lower the resolution for the video picture
sent.
Note:
Automatic adaptations take time. Configuring the client to fit the network and system capabilities
is always recommended.
Conference information
When moving the cursor over the video window, an information bar appears at the top. Clicking the
i
button opens
Conference information
, an overview of outgoing (transmit) and incoming (receive) traffic
data.
