The certificate that is used to establish secure communication with an IP/VoIP gateway using Transport Layer Security (TLS) is nearing its expiration date. By default, this event is first logged 30 days before the certificate expires, and then logged one time each day until the certificate is replaced. If the certificate that is stored on the Unified Messaging server is not replaced before it expires, the Microsoft Exchange Unified Messaging service will stop, and the Unified Messaging server will not be able to process any calls. To resolve this issue, install a new certificate on the Unified Messaging server and the IP/VoIP gateways that are being used by the Unified Messaging server.
