The ASA needs to have the correct CCM certificates uploaded (primarily the CAPF certificate) so that the ASA can bundle the CAPF certificate in the CTL file it generates.<br>
<br>You don't import the CTL from the CUCM into the ASA, you import certificates from the CUCM, and the ASA generates a brand new CTL file and signs it with its own key.<br><br>When you move phones inside to outside or outside to inside you need to delete the CTL file from the phone manually.<br>
