Shared Asterick PBX

Under the license agreement is it possible or desirable to setup an Asterick server and then sell VOIP services to multiple clients?

The following section of the license agreement reads:

2 GRANT OF LICENSE

2.1 Subject to your compliance with its obligations herein, Digium hereby
grants you a limited, non-transferable, non-exclusive, non-sublicensable
license to the Software for use with Zaptel software for internal business
purposes and not for resale, sublicense, or leasing to third-parties.
“Software” shall include any upgrades, updates, bug fixes or modified version (“Upgrades”) or backup copies of the Software supplied to you by Digiumprovided you hold a valid license key to the original Software and have paid any applicable fee for Upgrades.

Yes you can. Seems from the text here that you can’t sell the software its self or something of the sort (I hate legal mumble jumble).
