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.
The following code describes SIP 200 OK Response on the SUBSCRIBE Message.
SIP/2.0 200 OK
