Yealink Phone to Send Private IP Address on Register

[Ari]

I ran my own investigation into the issue.
In my case, setting:

Code:

network.ip_address_mode = 2

Disables sending the IPv4 address in the (as shown) during registration.

I would make a suggestion that if a phone has this set to option 2 and it still has an IPv4 address (irrespective of the IPv6 address) it should still send the IPv4 address.
