Nortel 8540 IP Phone connectivity

Question

Sign in to vote

We pulled out a Nortel 8540 IP Phone yesterday and tried logging into OCS with it. I keep getting this message when i try to sign in:

"cannot sign in . you do not have the necessary permissions. contact your system administrator."

it's got a valid IP address, and I can ping the phone and i can ping other things from the phone. are there any specific settings I need to check in order to connect this phone to OCS?

Also make sure that the user account is enabled for Enterprise Voice and assigned an extension if you are running R2.
