Hello,

I've been asked to support Call Manager and I am getting a "Registration: Security Error on phone" while reviewing the configuration of Call Manger, I ran across the certificate screen that indicated some certificates has expired.

call manager certificates expired.pngI see there is a regenerate option. Is there a process and order which these certs need to be generated?

 

Thanks for your help.

hi Experts,

 

I have few question on re-generate expired certs for UCM 12 (  not in mixed mode ) 

Following is the expired certs :

 

- Call Manager

-CAPF

-TVS

- ITL Recovery 

-ipsec

-Tomcat

 

* what is the impact if I let it expired ?

* Which order I need to do it first ? How many hours it take ,   we have 1 Pub and 5 Subs, 2 TFTP, 10,000 phones

*  What tool to check and delete ITL remotely ?

* If I don't restart phone after "Call Manager" cert  regenerate, will phone still registered?

* if I don't use Mixed mode, means no need to worry on TVS and CAPF  ?

 

Thanks,

C
