To configure Aastra provisioning

1. Add "aastra" to the "Provision models" setting under System » Configuration. If there is already a setting, add a ",aastra" to the end - for example "snom,aastra".
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. Go to Features » Provisioning, and edit the Aastra template to suit.
5. Edit a telephone line 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 done, save the telephone line.
6. Create a /etc/enswitch/www/aastra directory on your web server machine(s), and put the 57i.st and security.tuz files that Aastra provides in this directory. Make sure the directory and files are readable by the web server user.
7. Point the telephone to "http://<web server>/provision/aastra/".
