Digium HPEC License
License keys for HPEC channels are intended for use on a single server, and must be activated (registered) on the server they are intended to be used on.
It is extremely important that you carefully follow the instructions provided in README file for installing and backing up a new HPEC key for your Digium interface cards. The HPEC key must be re-registered if certain hardware changes are made to your server. An HPEC key can only be re-registered once without authorization from Digium, so it is important to back up your key files.
All purchases of HPEC fees are final. Refunds are not available for HPEC related purchases under any circumstances.
