The easy deploy is a redirection service that allows customers to register the MAC addresses of their VoIP phones on an Auto Provisioning Server and assign a redirection URL pointing to their own Auto Provisioning Server.
You can easily configure a lot of Yealinks, Snoms, or Aastras at once.

Go to your PBX interface:
Enter your logins: username and password.

Access the Extension section. Add a new extension.

Number  Enter the number you want to assign to the phone (except 112 (ambulance) and 113 (police)).

Mac Enter the Mac address that’s written on the back of the phone (begins with 000413xxxxxx).
Click on “…” and  PUSH the configuration.

After you pushed the configuration you have to press the easy deploy button.
Then restart your phone and the phone will fetch the configuration.

Always check if you can make external calls after the provisioning by calling a mobile phone for example.
