Auto Provisioning via Activation Code
In addition to the updating modes introduced above, users can trigger IP phones to perform
auto provisioning by dialing an activation code. To use this method, the activation code and the
provisioning server URL need to be pre-configured on the IP phones. This method works only if
there is no registered account on the IP phone. It is usually used for IP phones distributed by
retail sales. It has the advantage that the IP phones do not need to be handled (e.g., registering
account) before sending them to end-users.
