We installed on one of the units of GXW4248 and after 1 day users will start to loose dial tone.
Reset would help to restore dial tone but just for another day.
Unit worked fine under firmware for 365 days straight never had an issue.
We have still 4 units running firmware and i can see that older firmware using 2 times less the size of the memory.

the new firmware was installed after reset to defaults and reset to defaults was done after new firmware installed.
we manually reconfigured the unit after reset.

Thank you for your help
