User has 7960 with button 1 with extension 8001 single line. Then second button also has 8001 single line.
I assign corlist to ephone-dn 1 with extension 8001 only access to long distance.
Then I assign corlist to ephone-dn 2 with extension 8001 only access to local only.
But I found out that second button is able to call long distance too, it seems like inherit the ability of first button. Is that true??
If that is true, is there other way to workaround. I know I can assign extension 8002 to button 2, it will solve the problem.
