Problem: Connection Sounds "Dead"
Generally if a connection sounds "dead" then the level of background noise is too low. This can be due to an echo canceller being misconfigured or to a poor loss plan. Other causes are misconfiguration of the background noise level in a Voice Activity Detection / Silence Elimination or Line Echo Canceller function.
Impact
Users report that connection sounds "dead" even though normal speech is possible.
Resolution
Check echo canceller settings in Gateway. If VAD is being used then consider disabling.
