Generally the trick for this is to downsample the audio before encoding. 
You can ask ices to do this with a resample stanza in the config file:

    <resample>
        <in-rate>44100</in-rate>
        <out-rate>22050</out-rate>
    </resample>

You don't tell us what compression options you tried, but hopefully the 
resampling issue is the one you're missing.
