Is there a simple ROI calculator for IP PBX deployment? Where can I find a download of it?
We have an ROI worksheet here on this site. I wrote it. While it is not a calculator per se, it will provide you with what you need to examine for your ROI. Also, when you begin working with a vendor, they may have one that they can supply to you. I know Cisco has some great ROI tools.
