W52P Can't Config

Hi,

I have several issues with this phone.
1: The phone believes it is registered, but it is not staying registered (re-registering).

2: Whenever I try and make changes to the configuration, it tells me Talking, Please save config later. The phone is currently unused (even the status page shows this, and on the charger). The only way to fix is to power cycle the handset and the base. The phone is remote (VPN access), and I can't reboot it either via the GUI (talking, save config later).

3: It is unable to make calls sometimes even though it's registered fine.

Anyone have any ideas on how to fix this? I'm thinking I should just return it and get the panasonic or the snom instead.

Thanks
