Self-signed Callmanager-trust expires. Impact

[pablo.beraldi]

Dear,

I have a cluster that the callmanager certificate expires in June 20021 but the self-signed callmanager-trust expires in April 2021.

I wanted to ask you if the impact will be in June and if the callmanager-trust is automatically generated with the regeneration of the callmanager.

Thanks

When you upload or regenerate a certificate it's automatically uploaded to the -trust as well, if the dates don't match, you want to make sure you're actually looking at the same certificate, otherwise, it could be from either other server, or from a previous certificate.

There's a lot of literature around certificates, sign, regenerate and they also contain the usage of each certificate in CUCM.

Hi,

Please see below URL which explains the importance of each certificate and it's impact when particular certificate is invalid or expired:
