  • Hi,

    Yes and they have couple of options how to do this. The first option if they really have to stay with Skype for Business Online is to deploy the Skype for Business Cloud Connector Edition (CCE) on premises. The CCE you can connect to SfB Online and to a IP PBX, you might need a SBC between the CCE and the IP PBX. Since Skype for Business Online will be replaced by Teams this might to a complex solution for something that wont live that long. 
    Plan for CCE

    Another option is to migrate users to Microsoft Teams. With Teams you can deploy a SBC on premises and setup Direct Routing. The SBC will connect to your IP PBX and Teams and provide teams users with PSTN connection. You could also connect the direct to a SIP trunk.
    Direct Routing

    With Teams and Skype for Business Online you also have to option to buy phone numbers directly from Microsoft with Calling Plans, this option is only available in a few countries.

    Without talking to your customer and knowing anything about their requirements I think that the Direct Routing option is the best, but it depends on their current situation.

  • Hi,

    Agree with Linus.

    What’s your environment deployed in your organization, hybrid or online?

    If you have a hybrid environment, the following article could also be as the reference:
