Two potential issues here:

 

First if your network employs a web proxy to protect outbound TCP 443 traffic then you'll need to allow an exception in the proxy server for the Trio's MAC address as it does not currently support passing credentials to web proxies.

 

Second is that something is misconfigured in terms of Lyncdiscover and/or legacy SRV/A DNS records and the Trio is not being correctly directed to SfB Online during the server discovery process.  To test this you'll need to set the follow three parameters:

 

reg.1.serverAutoDiscovery="0"
reg.1.server.1.address="sipfed.online.lync.com"
reg.1.server.1.port="443"

    Jeff, thanks a lot for your reply. 

     

    I think it is the second, somwthing related to DNS. So I want to test with the settings you've provided. 

    But failed to locate these settings in web interface of RealPresence Trio 8800.

    Could you please clarify where I should enter these settings?
