We haven't fully tested the 286/287 provisioning yet since just added overnight, but it should work.
In another thread
The newer firmware is not fully compatible with the VOIPo network and will cause the device to be completely unusable with VOIPo service and it will be impossible to revert it back to the old version.
This is good to know in case anybody came across more RT31P2 devices,
or got some idea to upgrade them!
