Unsolicited Notify#

A D-Series phone allows a configuration via SIP notify messages. The user configures this feature with the settings /provisioning/sip/active.

The phone accepts only devices that are configured in the allowlist (former whitelist).

An allowed sender can provide check-sync messages, that also may contain a XML body. Furthermore the sender can send direct XML configuration snippets that are applied via the migration-machnism.

The phone reacts to the message above with a start of the provisioning service that will use the url directly. The elements url and dataAvailable are optional. The provisioning service uses the sources described in Provisioning, when no further infomation is given.
