Just started with UCMA development and going over the samples. I am using our company's Lync in Office365.
In the AVCall sample in establishing UserEndpoint I am getting Microsoft.Rtc.Signaling.TlsFailureException "Unknown error (0x80131500)". In the sample (in UCMASampleHelper.cs) a Lync Server FQDN is required for UserEndpointSettings. I am setting it to "sipdir.online.lync.com". Is it the coerrect FQDN of Lync in Office365?
If it is a correct FQDN - does the Win desktop that runs the sample need to have a specific valid certificate for Tls to succeed?Thanks,
David
