For the Astricon 2013, we created a little tool that lets you easily model Asterisk-based call centres.
QueueWiz is the first free web app for interactive, quick and accurate call center sizing, cost and revenue simulation. Insert your data with the intuitive interface, measure traffic intensity, expected wait times, agents’ engagement, revenue per call and per agent and even hourly margins. Save your simulation and share it via email or social media.
Completely free of charge at http://queuewiz.queuemetrics.com.
