Just a tip… pull your server off of AWS. You are going to have a bad time with quality and weird issues otherwise. From what everyone tells me… never install on AWS or Azure with ANY phone systems. Use a private data center or install it locally. I had one running in Digital ocean and had NOTHING but problems.

@jessy5765 makes good (if a little overly absolute ) points.

The system runs in a very small footprint in the local network, if you’re willing to do that. You can run the machine in just about any old workstation that can run Windows 7. It doesn’t require a lot of CPU or memory, and the network requirement is more about the audio than the ability of any reasonable 100M+ network card.
