Medium answer: Yes, you need to take care of the the network, the ISP to provider(fees & emergency trunks) and much much atention in the QoS and bandwidth to avoid “choppy” calls and bring a good service.
I just some information on trunks as well as getting bandwidth, if needed, with a static IP. I understand about the 911 now but I am unclear about QoS.
I have a sever based machine which is a little older but uses 64 bit technology. I looked up the minimum and preferred hardware specs for a smaller setup than mine. I am guessing that will have about 200 users or “extensions”. I think my hardware should be good enough for that. I’ll list specs on my profile.
I will have to do some digging in the forum to get some real good information.
Thanks for the inspirational answer, it put me over the top!
