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 address need to be pre-configured on the
IP phones. This method is normally 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.
