Newb Here, Sorry if some of this is basic

Hi, I have a small business and we are currently running 3CX for our phone system. I have experience setting up that system in a hosted environment, but am looking at potentially self hosting a FreePBX system. Currently we are running on a shared server through our VOIP provider and I am finding out there is a lot of the system that we can not access or control because it is global setting for all of the users, not just my company. To make matters worse, I got a notification that 3CX is raising prices due to new features they rolled out, but we can’t use these features because we are on a shared server.

Our use of the system is very basic. We only get a small handful of calls per day at this time, it is rare that two lines are being used at the same time. Most common would be I am on the phone with a customer and another customer is leaving a voicemail. Currently running soft phones and a few IP phones.

I already have a server running on a Dell Poweredge R730 with two ES-2670v3 2.30Ghz 24 core processors and 128 gigs of ram. I plan on running the FreePBX in a virtual machine. Is this server adequate to run our system?
