Yealink Forums

Hi,

I've currently got a fleet of TP-28 Yealink phones but are stuck on firmware 2.2.16.21 which i believe is very old.

As I've been reading through the forums, i believe you need to update these phones each release at a time and you have deleted the old upgrades which is fair enough.

Would you be able to share the respective files needed so that i can update these phones to the latest firmware?

Thanks,

Tim
