drgeoff thanks for the pointer -
I had found the expert mode to be a little finicky.
For example, changes to Line Keys seemed to be a 2 step process for me: Uncheck 'Obiltalk settings' -> submit -> change values -> submit
Also, as opposed to the web management interface, I was unable to see where I could define 'speed dial 99' values from Expert mode
Since this is a small SOHO setup, I don't think I will be needing provisioning. All I need to do is find how to disable it and keep using web management
Thanks again!
