Hi everyone,
A long time ago I used e-smith (around version 3 or 4..can't remember

). Anyways, I'm looking at it again for some client implementations (I only used it for personal use).
I know it is labeled as an Mitel appliance and the developer version is downloadable. Am I allowed to download and install SME on a client's system, or do I have to go through the official channels and purchase anything?
thanks.
