Not sure we have many options here ... we have a client with many 7921 phones in a noisy warehouse environment. They've increased handset volume for ringers, speakers, etc. though still complain in certain noisier areas that the volume is too low. I'm looking for possible options including additional volume increases, future firmware (firmware 1.0(5) - the latest - is loaded), headsets - including Blutooth headsets/adapters, etc..
Thanks in advance.
