I have configured the service in CCM 4.2 and I see it in my phone. However when I try to access the service I get the error below. What am I missing? Permissions in the server? Not sure (by the way, this is the first time I setup an IP Phone Service, so chances are I missing something somewhere)

"You are not authorized to view this page due to an incorrect userid/password pair or your authorization expired.

Press "Exit" and then "Services" button to start again"

Any help will be greatly appreciated.
