Preparing audio files for 8khz

In preparing voice files for a final sample rate of 8kHz what can I do to ensure that the voice remains as warm and untinny as possible.

I am saving down files for upload to a telephone system that only supports 8kHz wav format. While I have recorded at 41kHz it is obviously losing a lot of quality in the down-sample. While I realize there are obvious limitations with the final format and eventually it will sound telephone-y, is there artificial processing I should carry out to balance this before they are down-sampled, e.g. bass boost, equalization to make sure that they sound as natural as possible even at this rate. I have already normalized all of the files and have good levels to work with.
It is similar but opposite to this question, which has already helped
I am using Audacity - thanks!
