One of the easiest ways to set up an IP PBX system is to find a company that offers a hosted IP PBX solution. The idea here is to let the host company set up everything: ring groups, extension dialing, conferencing, etc. All you do is purchase the service for a monthly rate and then configure it yourself over the web. There's little set-up or networking required on your end.
