Dear Community,
I'd like to share with you my problem with Cisco DX650 during the Secure call.
My CUCM v. 10.5.2 and I'm succefully implemented the secure certification on all phones with secury profile for each model .
at the moment I did the same for the model DX650 and trying to reach a call from cisco 7975 but no success.
I'm receiving the call and when I push ANSWER the phone going to reboot and when I'm trying to call from DX650 to Cisco 7975 it drops immediately and reboot.
I tested the encrypted call between other phones, Cisco 7975 to Cisco 9971 , Cisco 9971 to Cisco 7821, Cisco 9971 to Cisco 7975, everything is OK, I'm getting the LOCK icon during the call , both side can hear each other.
Would like to mention that on Cisco DX650 - Settings/ Security/ Enterprise Security Settings - LSC and TRUST LIST _ CTL AND ITL File are installed /
Where do I need to look at to fix this problem ?
