to be aware of its connection to the UCM and take the appropriate actions such as raising alarms,
sending notifications, etc.

can provide the following information:
• extension – UCM extension number
• name – extension display name / CID name
• mwi – MWI state
• permission – permission level of the extension
• cfwt – call forwarding always number
• dnd – DND state
• language – display language of the extension in ISO 639-1 format
The UCM should respond with either 200 OK or 404 responses.
