Skype for business external implementation RRS feed

  • Question

  • Dear all

    I have just implemented skype for business 2019 on premises "enterprise edition", all on one server connected to a SQL database

    Everything is working fine internally [IM, voice, video, sharing desktop]

    Externally "outside the organization", only the IM is working, anything else is not working.

    Can you please let me know what are the ports that needed to be published through the firewall, as well the external DNS records needed to be created externally???

    About the external DNS records you could refer to the screenshot:

    In addition, you could refer to the following official document to find the details: Port and protocol requirements for servers
