Some devices do not support MDA. You might be able to log in to these devices using the same extension that you used to log in to Avaya Workplace Client. However, other MDA functionality, such as the ability to answer a new call or join an existing call, might not work properly.
Video escalation
When more than one device is on a call, you cannot escalate the call to video. If additional devices drop from the call and only one device remains on the call, you can escalate that call to a video call.
When a second device joins a video call, the video screen becomes blank.
An EC500 device cannot escalate to a video call at any time even if the EC500 device is the only device on the call.
