To configure Grandstream provisioning

1. Add "grandstream" to the "Provisioning models" setting under System » Configuration. If there is already a setting, add a ",grandstream" to the end - for example "aastra,grandstream".
2. Set the "SIP domain" custom setting for the system rate plan (normally called "Your own rate plan") to be the hostname or IP address that telephones should register to.
3. Wait one minute for these setting to take effect.
4. Edit a telephone on the Enswitch web, and set the MAC address. If there are multiple lines on the same physical telephone, the accounts can be suffixed with "-1", "-2", etc. For example:

   00:11:22:33:44:55-1

   for the first line on physical telephone 00:11:22:33:44:55. When you save, update, or delete the telephone, the Enswitch web will generate, regenerate, or delete the files in /var/lib/enswitch/provision.
5. Point the telephone to http://<web server>/provision/grandstream/ht502/ or http://<web server>/provision/grandstream/ht503/ as appropriate.

To modify the template used

• Copy /opt/enswitch/current/templates/en/provision/grandstream/* to /etc/enswitch/templates/en/provision/grandstream (you will need to make this directory), edit them to suit, then re-save any telephones on the web. The Enswitch web interface will replace the <TMPL_VAR> with the data from the database using the HTML::Template Perl library.
