I have received the following on my Exchange server 2010. Any idea ?
10.0.x.81 is the Exchange
10.0.x.41 is the Lync server
The Unified Messaging server failed to exchange the required certificates with an IP gateway to enable Transport layer Security (TLS) for an incoming call. Please check that this is a configured TLS peer and that the certificates being used are correct. More information: A TLS failure occurred because the remote server disconnected while TLS negotiation was in progress. The error code = 0x80131500 and the message = Unknown error (0x080131500). Remote certificate: (). Remote end point: 10.0.x.81:5061. Local end point: 10.0.x.41:55181.
