TDA 30 digital phones truning "off" and "on" 1

[avayacy]

I have been experiencing a strange problem with a clients system for some time now. A TDA30 v2 sometimes turns "off" and immediately "on" again all it's Digital phones (6 phones). The phones loose all power for a second or two and afterward they function normally. The system doesn't reboot as the phones come up again in seconds. Every time this happens there is the following entry in the systems error log:
Error Code: 000
Sub Code: 10000
Error Message: MPR WDT overflow
To me this seems like a software error and I am thinking of upgrading the system to a newer release, but if somebody has any ideas I would be glad to hear them.

There was another post about watch dog timer not too long ago
upgrading may not solve your problem .You may have to ship that ksu off to Panasonic.
