[cisco-voip] Self-Signed Certificates on CallManager

[Carter, Bill]

I don't know much about certificates and CA....I understand web sites etc. that use SSL have registered their certificates with a CA. When we install CallManager it uses SSL with self-signed certificates. When web'ng into UCM the browsers display the a certificate error. I believe this is because the certificate is not registered with a recognized CA.
 
I understand, if an organization already has a business relationship with a CA, a "valid" certificate can be loaded on UCM. Is it possible for Cisco to provide certificates on UCM that are registered with a CA so we don't get the browser errors? Or is it a requirement that the end user obtain valid certificates for their own servers? Like I said, I don't know the mechanics of how certificates work.
 
Thanks,
Bill
