IP331 saving changes to handset volume

I have some IP331s on firmware and configure them through the web interface rather than using a provisioning server / config files.


Users are complaining that the handset volume resets to deafult settings after every call.


Knowledge base says this is a "feature" mandated by US Gov't  but can be overridden with a parameter entered in the sip.cfg file. However I dont use  any such file!


Is there a way to disable the handset volume reset through the web interface ? Cant see any reference to this
