3CX
With 3CX Phone System the provisioning of IP Phones is done fast and easy.
You can configure your IP Phones and assign an extension to each phone. In order to do this, you must provision the IP Phones. Although phones can be configured one by one manually using their web interface, this is impractical as it leads to many errors and deployment time is increased drastically. Furthermore, ongoing management of the IP Phones is almost impossible.
Therefore 3CX requires you to use phone provisioning. Using this method you instruct the phone to retrieve its configuration from 3CX Phone System. Once you provision a phone, the phone will automatically configure itself correctly and you will be able to manage the phones centrally and remotely and without having to log in to the phone’s web interface one by one.
