Panasonic Answering Machine Volume Adjustment

From what I have seen in these answering machines, there was no control of
such that your are requesting. Most likely this parameter is burned in to
the machines software, and would not be accessible. This is why the
Panasonic tech was not able to have the solution.

The only option you have is to send the machine to Panasonic, and they will
be able to do a performance test to tell you if the machine is actually
defective, or if it is normal in its operation. If you send the machine to a
local service centre, they may not be of much assistance with this type of
problem.

==========================

Sorry if this is a duplicate, I didn't find the message today that I posted
yesterday.

Is there a way to increase the playback volume when retrieving messages by
calling a Panasonic model KX-TM100B, answering machine?  The volume control
on
the unit adjusts the internal speaker, but doesn't affect the volume thru
the
phone line when I retrieve messages while traveling and calling the unit.
Panasonic tech. help had no advice.
Thanks.
