The provisioning server or any other entity replies with a 200 OK message to the
SUBSCRIBE message (see below) and sends a NOTIFY SIP message with the
provisioning URL in the message body as shown below. (The provisioning URL can be in
any format as described in the Administrator's Manual).
If no response is received by the provisioning server, the phone resends SUBSCRIBE
messages for 5 seconds.
With the above method, the phone uses its built-in auto-provisioning mechanism while the
provisioning information is retrieved through the NOTIFY message.
