Ignoring unhelpful snobbish remarks from the peanut gallery... Your ratio will depend largely on the usage by your users. In a busy contact center where your users/agents will be on calls nearly 100% of the time, your ratio will need to be closer to 1:1. However, if the installation is for a school where most of the staff (teachers) are instructing in the classroom or otherwise away from their desks, you can get by with a higher ratio like 4:1. As always, you build your system with room for expansion in the event you need additional resource availability. Also, ensure your customer/client understands the limitations of the number simultaneous calls. If you don't tell them and they find out the hard way, you'll be in a world of hurt.
