Yealink Phone to Send Private IP Address on Register

[Clan_Yealink]

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?

Hi Sir, how are you today？

This is Clan from Yealink Technical Support team, nice to work with you.

There are configuration statements in the phone to control whether the IP address is in the Call-ID.
Statement: account.x.call_id_no_ip_addr.enable = 0 (X is the account number)

Any queries, please feel free to let me know. Thanks.

Best Regards!
