Poly VVX 350 USB Headset volume will not persist across calls

[Brunoswims]

I have a Poly VVX 350 using a Poly Blackwire c5220 usb headset.  For some reason the call volume will not persist across calls.  It always returns to default volume.  The config file shows that <WEB voice.volume.persist.usbHeadset="1"
/> is set.
