How to verify generation of phone

[centuric]

How can I tell if yealink is a:

Yealink V70 T2X Model
Yealink V70 T3X Model

Yealink/Dreamwave T2X Model
Yealink/Dreamwave T2X V71 Model
Yealink/Dreamwave T3X Model


I can obviously tell whether the phone is a t22, t38 or t28, but I can't figure out what generation the phone is, any insight will be greatly appreciated. Thanks.

Dear User，

Thanks for your kind attention on Yealink products.

We can judge this from firmware version. Press OK button on keypad, you may find firmware version. For example:28.72.0.25.
Here first part 28 represents model number SIP-T46G, second part 72 means the firmware generation, this is a V72.
