Looking for a opinion we have cucm cluster with 7 nodes pub, 4 subs and 2 tftp servers on the publisher only the call manager cert is set to expire on the subs the same cert os fine till 2020 .
Part of the processs in the docs is to reset ll phones which are 3800 in total since the cucm cert is going to be regenerated on the pub only is it necessary to reset the phones as none of them can register to the pub the callmanager groups dont have the pub in them ?????
