Cisco VCS - Server Certificate

[tornygard1]

I get the warning "Insecure certificate: This cystem is using the default server certificate. We recommend...." On my VCS`es

1. Is there anything I have to take in consideration related to Endpoints or other VCS`s  (this is a cluster) before uploading a New certificate?

2. Will communication between endpoints be affected?

Hi,

If you are looking to get your certificates signed by your own or a public CA i would first make sure your servers have hostnames and relevant DNS records configured. In addition to this, if you plan on using collaboration edge (MRA) you should take a look at the additional SANs required for this:

You shouldn't have issues with endpoints being affected, in my experience the certificates have only affected collaboration edge.

Thanks, Simon
