Hi Birni,
Hope all is well
Unless something has changed in CUCM 9.1, the user can enter a restricted
(by Forward CSS) number all they want via ucmuser but the call forward will be blocked
by the CSS and a fast busy returned to the caller. Not elegant but effective!
You could also set the Enterprise Parameters>Show Call Forwarding" value in CCMUser Parameters to False
so the users don't have the option at all.
Cheers!
Rob
