Hi All,
I spoke too soon

I can change the time zone to GMT -5 and save the changes, but it then reverts back to GMT

I log back into the SPA2000 and change it again and it shows it has beeing saved, refresh the page or log in again and again it's back to GMT

Any ideas? It couldn't have anything to do with the auto provisioning could it? A look on Linksys' or Sipura's site brings up nothing. Just to correct one thing in my original post it is actually a Sipura not Linksys SPA2000 although I know they are meant to be the same.
Regards,
Del
