Anyone have the link for 3cx SBC for v15 set up instructions? The documentation I can find is all for v16 and upgrading is not an option at the moment. I don't have the "Add SBC" button on my SIP Trunks page.
Thanks. I've managed to get the SBC installed on the windows computer and entered all the details, secret key, etc. It's on the 3CX management portal I can't see where to add it there.
You don't add it in the management portal. That's a v16 Update 2 feature. In v15 there was no visibility of the SBC in the management console. You just configured it with the information as you did now it connected (or didn't). You can check the sbc logs or just plug in a phone and see if the PnP provisioning shows up.
