[Asterisk-Users] Aastra firmware 1.3.x (Far-End sound level issue)

I know this is done by setting the handset tx gain: and handset sidetone 
gain:  parameters via a config file from a tftp server.
I was looking for working example values though, as I seem to be unable to 
get it right.
See below message which has surfaced in this list (and I received the exact 
message when complaining at Aastra):

The audio issue you mention is a known issue as a result of some audio
adjustments we've added in 1.3.
The audio properties have been adjusted slightly in the 1.3 firmware to
reduce side-tone and echo on the local and far-end equipment. In line with
these adjustments we have added some configurable parameters that allow
users to configure their own audio settings to best suit their needs. These
parameters are only configurable via the .cfg file via a TFTP server and use
the following syntax:

headset tx gain:
headset sidetone gain:
handset tx gain:
handset sidetone gain:
handsfree tx gain:

Each of these parameters can be adjusted by + / - 10 db

Example 1:
headset tx gain: -5 (reduce the headset transmit gain by 5 db)

Example 2:
handset tx gain: 10 (increase the handset transmit gain by 10 db)

Please try adjustiing these parameter and let me know if this resolves the
problem.

^^^^^^^^^^^^^^^^^^

Please let me know if you get the far-end soundlevel to a decent volume.

With regards,
