To configure Polycom provisioning

1. Add "polycom" to the "Provisioning models" setting under System » Configuration. If there is already a setting, add a ",polycom" to the end - for example "aastra,polycom".
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. Set up a tftp server serving from /var/lib/enswitch/provision.
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 the tftp server.

To modify the templates used

1. Edit /var/lib/enswitch/provision/sip.cfg on any web server machines. This is a symlink to /opt/enswitch, and we recommend against changing files under /opt/enswitch (they will break on Enswitch upgrade), so you should delete the symlink, copy /opt/enswitch/current/etc/polycom/sip.cfg, and edit the new file. Changes to this file take effect immediately.
2. Copy /opt/enswitch/current/templates/en/provision/polycom/* to /etc/enswitch/templates/en/provision/polycom (you will need to make this directory) on any web server machines, 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.
