Allow commination between two SFB Installations in trusted domains RRS feed

  • Question

  • I've got a strange situation here.  I have two trusted domains which can access one another.  Each has their own SFB install.  I am trying to find out how to allow the users on each Skype install to IM users on the other.

    Most of the articles I am finding regarding this, seems to deal with WAN issues, non-trusted domains, etc.  Does anyone either know, or have a resource which explains how to enable connectivity between these two SFB installs?

  • Hi 

    Are these two SFB deployment on two different forests?

    If yes then you would need to set up federation between the two SFB forests

    If single forest > Are both SIP Domains added in the topology?

  • Each SFB deployment is in a separate forest, but both are trusted and have direct connectivity to one another.

    I assume that we need a federation, but I can’t find out how to do that without the use of Edge servers, which I shouldn't need if the two forests can communicate directly.

  • Federation is the only way where two SFB forest can communicate over Lync clients (IM/Presence and all)

    This cannot be done without Edge servers at both ends 

    Edge servers at both sides  will help you establish federation

  • Hi Ninetail,

    Agree with Akabe.

    As a supplement, for this situation, you need to do federation, and if you want to do federation, you must deploy Edge server, because Edge server is the required component for external access.

    Here is a blog about setting up Lync federation in Lync Server 2013, it’s similar to SFB server 2015
    https://technet.microsoft.com/en-us/library/jj204800(v=ocs.15).aspx

    This article describes the external access for Lync server 2013 but same to SFB 2015

    Hope this reply is helpful to you.
