What are the system requirements for multiple simultaneous lines or calls?

We cannot provide an exact answer because it depends on so many factors. These factors include, the CPU speed, RAM, hard drive speed, network connectivity (for VoIP), the complexity of the OGM structure and whether or not you are compressing audio anywhere.

Our suggestion is to install a small scaled version using the trial version of the software. Run it with real call(s) then have a look at the Windows Task Manager to see percentage CPU, RAM and Network usage. Then you will have an idea about how it will scale up by multiplying usage
