        Microsoft.Rtc.Internal.Sip.TLSException
    Possible cause
            The SSL certificate was not created with the correct cryptographic
                service provider and key spec. The KeySpec property sets or retrieves the type of
                key generated. Valid values are determined by the cryptographic service provider in
                use, typically 
Microsoft
 RSA.Possible solution
            Verify that the Provider, ProviderType, and KeySpec values are the
                same as the examples below or the CA must reissue a new SSL and appropriate provider
                and key spec values. 
- On the computer that hostsBEMS, open theWindows PowerShelland type the following command:certutil.exe –v –store “my” <name of ssl cert>” > c:\temp\ssl.txt
 - In a text editor, open thessl.txtfile. By default, the ssl.txt file is located in<.drive>:\temp
 - Search forCERT_KEY_PROV_INFO_PROP_ID.
