V73 IPV6 missing privacy extensions

[MarioG]

I don't know if this is a bug or a missing feature. When using IPV6 the T48G is showing only it global unicast IP address to the SIP server. It should be showing a different address that randomly changes per the IPV6 privacy extension standard. Without that, the global address is exposed to the internet for anyone to access. The privacy address changes so no one can use the address too long to hack into the phone.

Every OS such as Linux, OS X and Windows does this. Also, most devices such as all IOS devices use privacy extensions. A phone system should be made as hack-proof as possible and privacy extensions are very important.

We use prefix delegation to assign the IPV6 address and all our other devices generate privacy addresses that become global but for only the assigned time, usually 24 hours. Privacy extension also are part of the SLAAC assignment standard.

I urge Yealink to implement this if not already done to improve phone security.
