Description (partial)

Symptom:
When through 8831's MIC, it sounds like the user is far from the phone.
The MOS value of the call is perfect and the sound is loud and clear. It's just not as natural as other phones like 7937.

Conditions:
A simple call from 8831(user A) to another phone(7962 for example, user B) registered on the same CM(not through WAN).
