Cisco CUCM call forward questions

We recently migrated to a new CUCM server and upgraded from 9.X to 10.5.X...  We've given our users access to the Self Care Portal.  While limited in what they can do, the main feature is for them to be able to forward calls.  The issue is it doesn't currently work without me going in and manually adding a CSS for the numbers they've forwarded under the Line settings.  For example Call forward no answer has the number they've added in their SCP but the CSS stays at <NONE>.  

I've played around with the Call forward Activation Policy under Service Parameters some but can't get this to work.  I tried "with configured CSS" and "Activating Device Line CSS". I've been told I can edit every line using BAT.. is this the only way to achieve making Call forwarding work?

"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

If either the CSS of the IP Phones, or the CSS of the Line have access to the telephone number users like to forward their phones, meaning, if they can dial that number from their ip phones, then you just need to go into System > Service Parameters and find the Default value for Call Forward Alll. Choose Activating Device Line CSS to apply the same values on forwarding all, as the system would apply when making a direct call. This applies system wide, so it is a one click change to affect all phones.
