asterisk users - Mar 2012 - Grandstream GXP20XX BLF lamps stop working soon after a phone reboot.

Any one having this problem.
The Grandstream Firmware revision is 1.2.5.3.

We have the registration time set to 5 minutes, and every time after a
reboot, the BLF's will initially indicate the correct state, then stop
working a few minutes later.

The workaround has previously been to reboot twice. The 2nd time just after
the BLFs' stop working.

I have a patch for this, that's available at
