[asterisk-users] volume control and setting volume on transfer

I've been trying to resolve a volume issue. I have an analogue SIP phone 
that has low gain on its microphone. This can be resolved by putting the 
following in its extension config:


The problem is that the caller to this extension will be making attended 
transfers and the change in channel volume distorts the voice prompt 
"transfer" and the subsequent dial tone.

Is there a way that I can redefine "atxfer" in features.conf such that 
the volume of the channel is set back to 1 before the transfer is made? 
I would like to do the opposite after that, ie. return the volume of the 
extension to 4 when the transfer is finalised with "atxferthreeway".

If anyone can help with this or has other suggestions, please let me know.
