My CUCM version is 184.108.40.20600-66. Both ceritificates of CallManager -trust and CAPF-trust(issued by CAP-RTP-001) will expire. According to Cisco documents, it is NOT possible to regenerate them. I have some questions as follow.
1. What impact on CUCM if the certificates expire? I don't apply security profile on IP Phone.
2. Can I deleted the expired certificates?
2. How to generate new certificates to replace them? I don't want to apply for new ceritificates from thired-party.
