    Have you have anyone report that Lync 2013 conference calls do not work with UCS 5.1.1 using BToE (2.1 and 2.3)? Error message is

    “An error occurred. When contacting your support team, reference error ID 603 (source ID 239).”

      Hi Thomas, i havn’t seen that error yet on VVX series yet.

      but from reading the Release notes for BToE 2.3:
      VOIP-89004 In a BToE mode, establishing a local conference is not available when the phone is paired with your computer.
      Workaround: You can make conference calls from the Lync client, or you can disable BToE on your phone by pressing the BToE soft key and selecting Disable before making a conference call on your phone.

      Is that the problem you are facing?

        I’m not able to make a conference call from the Lync client with BToE. Disabling BToE and making a conference call from the VVX works. Lync conference calls from the client worked with UCS 5.0.2. Thanks.
