I have one very “quirky” site I manage that has a dream machine, utilizing unifi access points and switches. We run Grandstream 2614 phones connected to a UCM cloud instance and have more connectivity issues than I have seen at any other site with similar setups…
I did not set this network up, rather inherited it, and I believe there are some quirks with the dream machine first and foremost / it may even be slowly dying as it weekly will disconnect from the Unifi management portal, though still accessible / can VPN in, etc, which is beside the point and will be investigated…
My root question - for those of you doing similar things, have you had similar issues with phones being unreachable / and have there been any notable tweaks you have had to make in the dream machine to make things work more reliably?
