Hi, I'm trying to configure a NEC ITK-12D-1P (DT900 series) phone on a Yeastar P550 PBX. The system requires firmware version 05.03.04.99 or later, but I haven't been able to find it anywhere. Can anyone in this forum help me? Thank you.
 
Rosomax did you get the phone working ok on the Yeastar? I've not tried this yet but hoping to do soon on the P550 system
