  • I would suggest you

    - enable logging on the lync server and review the logs
    - enable logging in Lync client on both sides, retry, and use the Logging Tool to view the client logs. They are saved in c:\users\<user>\tracing

    It might provide more information on the reason why the call is not completed.

  • Dear Ruben,

    Issues is only the Computers which are domain-joined to mycompany.com domain (Note: i didnt have any domain admin rights here, its my company's live domain ) , 

    My Lab domain is uclync.com. The users from mycompany.com domain are able to make desktop shairng, IM chat, Whiteboard etc except the Lync Call. we all are in the same network. The error i mentioned at the top is shown when i call to users which are coming frm mycompany.com domain-joined computers.

    Note: There is no Enterprise Voice and Edge Services installed at uclync.com domain.

    What is clicking in my mind is that , is it a restriction of SRTP/RTP ports at mycompany.com?

    So i have totally disabled firewall of one user frm mycompany.com domain still the same problem.

    Where i have to allow that traffic to be routed at mycompany.com?

    Any idea, why is that happening?
