TX audio gain

any settings to increase the TX audio gain via config or cli?  

we've got a massage therapy customer that needs a little more gain.

Thanks!

EDIT: Sorry, misunderstood your question!

No the audio in a phone call. The grand stream boxes we used to use, we would amplify either tx or or rx volume -/+ up to 9db

I haven't done it myself, but I think this is what you are looking for:
