Polling Request To Bridge A Firewall
When the provisioning service is located behind a firewall, or in a DMZ, it may have no possi-
bility to send a contact-me message to the phone. To enable provisioning service driven inter-
actions despite this limitation, the phone can be configured to periodically poll the provisioning
service, or a special proxy, for new messages. This configuration is done by the provisioning
service, for instance, at phone startup; for the relevant data items, see Section 6.1, "Provision-
ing Service Related".
The polling request is an HTTP GET request which contains a particular key/value pair to iden-
tify the phone. The key is
device-id
, and the value is the phone’s MAC address as a para-
meter. The structure is as follows:
http://<target address>/dcmp/contact-me?device-id=<MAC address>
Example:
http://provisioning.mycompany.com/dcmp/contact-me?device-
id=12:34:56:78:9a:bc
