>If you're using Express Talk, run the Audio Set-up Wizard and see what the mic levels are
Hmm, the audio wizard must be specific to Windows versions. Both computers are running Express Talk phones on OSX (10.5) and no audio wizard is available under application preferences.
Both are using standard system line outs and the volume on these should be good as the users run iTunes and report no problems there. Also, the levels are good for external calls.

Ah ok. Well, happy to provide some diagnostics if it is an application bug but could be another problem there though - logging in Linux Axon doesn't appear to work either. Have turned on SIP logging via the web admin panel but no files appear here or in the logs directory on the file system.
