We have 2 of the Grandstream GXW4224 ATAs at the same site and they seem to lock up every 2 weeks or so within minutes of each other. The network connection is still up because the units can be pinged, but the Web UI and SSH access don't work. In addition the display shows "VoIP Failed" and the analog ports are unresponsive. The units are on a properly configured VLAN.

Firmware version is 1.0.21.1 and although beta version 1.0.23 is available, the release notes don't indicate this particular bug is fixed.
