The Network Quality Meter is visible only while a call is active. During a call, LIVE continuously monitors the available quality of the network. It is normal to see minor fluctuations during a call. Green lights in the meter mean the network quality (and therefore voice quality) is high. Yellow means network conditions are difficult, and you might experience decreased voice quality, although the LIVE software will provide as much voice quality as possible even when the network is experiencing difficulty. Red means that the current level of available network quality is so low that you would not be able to carry on a conversation.
