CME: Cisco 8945 CTL is not installed

Hi,

I'm running CME Version 15.2(4)M3 with SRTP and TLS. I have deployed a bunch of Cisco 7942 and Cisco 8945 phone. After enable encryption all Cisco 7942 installed the CTL and LSC certificate but Cisco 8945 didn't installed the CTL and LSC certificate.

The Cisco 8945 phone is able to register without encryption so it doesn't look like a TFTP problem.

Cisco 8945 status message:

CME: Cisco 8945 CTL is not installed

Have you tried deleting the CTL File on the 8945 to see if it will install a fresh certificate?

The trust list update failed typically means there is an ITL/CTL File installed already, but the source of the 'new' ITL/CTL file is not trusted.

I recommend you have a look at the following document to get some additional background:

Given you are working with CTL files I recommend you read the following book from Akhil Behl:

"Securing Cisco IP Telephony Networks"

CME: Cisco 8945 CTL is not installed

Hi Stephen,

I tried a hard reset but at the end there's not a CTL or ITL certificate installed in the phone. I don't why the phone is not able to download the CTL files when Cisco 7942 is able.

I have some weeks trying to decide to buy or not buy the book, at least for me is very expensive .

Regards
