I could see my call manager is having tomcat, tomcat-trust and Call Manager certificate as CA Signed and they are going to expire. To renew the same, i have to regenerate the certificates and have to give the same to CA to be signed and they will provide us the root and intermediate certificates to upload it into the server.
Can someone tell me what will be the impact if i not renew the tomcat and Call manager certificates?
What will be the extension for root and intermediate certificates given by CA? is that .csr or .pem or something else
