RE: Cannot register new T42s anymore

The new ones seems to ignore the response Status-Line: SIP/2.0 401 Unauthorized
and do not reregister with the credentials included.
It tries to register again and again but never sending credentials to the server.

It sends always this registration (replaced name with XXX), but always without credentials.

Update: Downgraded firmware to 66.81.0.70. Works flawless with this firmware version.
Cannot make tests with all firmware versions, but 66.81 works.

Is there something wrong with 66.84?
