4.3 Configuring Automatic Provisioning via SIP

SUBSCRIBE and NOTIFY

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.

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:
