Yealink Phone to Send Private IP Address on Register

[Ari]

A really helpful feature of the < 83 firmware was to send the private IP address of the phone on register. This is helpful for locating and administering a phone in a network.

Code:

On the right is a registration from a Yealink phone on 81 firmware and in the "Call-ID" header you can see the private IP address sent. On the left, you can see the 84 firmware does not send the private IP address.
Is there a config on the Yealink to change that?
