I have to be honest...none of them are working very well on my VZN 6800.

The .csv files in the first post have the following issues:
1. The volume doesn't seem to improve (get louder) at all
2. On speaker phone, the sound is "choppy"...in other words, i was testing with "hello" and "can you hear me now". I could only hear "-o" and "-ear now".

we're getting there though!
