I have Office 365 E1 plan to get Exchange and Lync.
Now we want to be able to call the landlines with Lync. I suppose I need to setup a local Lync server for this?
We only have one public IP, so I'm actually worried that this setup will require additional SSL certificates, as we've used the public IP once already for AD FS?
I've searched for a while now but I can't find a good walkthrough of this setup. Has anyone done this? How was the experience?
