  • Question

  • **New to Skype for Business**

    We have Skype for Business 2015 (2 Servers) and everything looks good. Internally we are able to connect (IM) 

    Now we have certain request to make sure our parter company should be able to initiate IM

    Our domain is abc.local (internally) and abc.com externally 

    Skype Servers are internal to our domain Skype01.abc.local

    Partner external domain is def.com externally 

    What do i need to get our Internal Skype for Business users be able to find and IM our partner company users (i guess over internet and from within our local network)

  • Hi,

    Based on the way you've worded your query, I'm going to assume that your networks are completely separate; i.e. both companies are in separate forests, and that there is no forest trust between the two companies.

    In order to communicate (federate) with the partner organisation you need to have a Skype for Business Edge server deployed, and a reverse proxy solution (many things are capable of providing reverse proxy functionality such as WAP, Kemps, Sophos UTM etc.). Those are the only 2 additional components you need in order to extend your environment beyond your perimeter network and allow for federation and external access. You mention that you have 2 servers deployed, but you didn't state what server roles they are so one could well be an edge server already perhaps? In addition to the server roles, you'll also need to plan and implement the appropriate firewall rules and public certificate requirements.

    That takes care of your organisation, and although you didn't mention what the partner organisation have, I'm assuming they already have Skype for Business set up for external access, and its just your side that needs completing? If not then the same requirements also apply to them.

    Both organisations will need to either be openly federated, or explicitly define the other as a federated partner - this is configured in the Skype for Business control panel. Once you've met the external access and federation requirements in the link below you'll have no problem being able to communicate cross organisation.

    I've guessed at a few things there, so please correct any parts of the scenario I've got wrong. Please review the planning section in the TechNet library around Skype for Business external access and federation.

    Kind regards
    Ben

  • Hi Kitaab,

    Agree with BenDonaldson.

    In short, you need to do federation with external users, and for federation, Edge server is required because Edge server is the required component for external access.

    The main process to configure federation, Setting Up Lync Federation in Topology Builder and the Deployment Wizard, then configure Federation with Partners, here is a blog for your reference, it’s similar to SFB server 2015

  • Hi kitaab,

    If you use SFB server, you need AD environment, so you need to install ADDS server role.
