Hi,
I need to regenerate expired certificates on a live CUCM 9.1 cluster. Could I just sanity check on service impact, by which I mean impact on calls and on SCCP and SIP registered phones? My understanding is that there should be no impact when regenerating Tomcat and IPSec certificates. Is this correct? Last time I did this was all within a change window so I didn't care if the phones did a soft reset, and I don't remember if they did.
Thanks, Tony S

I concur with Slavik (+5), you need to list which self signed certs you are re-generating as they all provide different purpose thus have different impact, i.e. regenerating callmanager certs for example or even deleting expired callmanager trust store certs will cause phones to reset due to ITL cert updates.
