I ran into an issue where 7961 and 7941 phones are unable to register to ccme router 2811, looks like a .tlv file that begins with CTLSEP is missing at the cme router.

Tried to factory reset the phone, installed various IOS images on the 2811 but still not working

If any one has dealt with this issue previously, please let me know how you fixed it. Thanks

Hi

Don't worry about the CTLSEP file; it's basically the phone trying to download a certificate trust list in case the CME/CUCM it is trying to register to is configured in 'secure' mode:

Secure and Nonsecure Configuration 
The Cisco IP Phone 7960 and 7940 platform supports configuration-file authentication, certificate installation, and device authentication with the call control unit. By default, the phone is nonsecure until the phone detects that it needs to take additional steps to configure itself in secure mode. The initial step in this determination is through a CTLSEP MAC file request upon bootup (for example, CTLSEP003094C25D2E.tlv). The CTLSEP MAC file is a certificate trust list, which if populated, contains information about the servers to which the phone is attempting to connect and whether the server connection will be secure or nonsecure. 
The CTLSEP MAC file is the first file requested in the universal application loader, followed by the additional six configuration files in the hunt algorithm defined in the "Universal Application Loader" section. If the CTLSEP MAC file is present, the phone proceeds with additional security actions regarding phone and server communication; if the CTLSEP MAC file is not present or is empty, the phone proceeds in nonsecure mode with the hunt algorithm.


Perhaps post up your CME config.

Have you configured 'create cnf-files' under telephone-service?

Are you debugging TFTP from the router, or from the phone status messages screen?

Hey

Problem is still there, right now there are two phones 7960 and 7961, 7960 is fine, only 7961, if I remember correctly, 7941 also had this issue.

Yes, ‘create cnf-files’ has been configured under telephony-service.  The debug tftp event output may indicate that CTLSEP….tlv could be the issue.

Searched for other postings, this post has a similar issue. https://supportforums.cisco.com/message/337619#337619.  my temporary work around is to use this 7961 to register to call manager and use another 7960 phone for br2.  But I really want to find an answer.  Thanks.
