SIP SUBSCRIBE and NOTIFY Messages
If the provisioning information (e.g. Option fields 66/67/160) is not provided by the DHCP
server, the phone sends a SIP SUBSCRIBE message to the multicast address
224.0.1.75:5060 as shown below.
Note:
If the provisioning server supports using SIP SUBSCRIBE and NOTIFY
messages and the device receives the provisioning URL in the NOTIFY
message, the automatic provisioning mechanism then periodically tries to
retrieve a new firmware/configuration according to the information
provided.

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 five 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:
