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

Not yet, i did not get the correct firmware , i will let you know if i will be able to make it work.
 
Nec-Sip or SIP firmware, do you know which one it works with Yeastar?
 
Is it even worth the effort as you end up with a pretty dumb phone and you won't be able to program keys to the phone! a cheap E bay Yealink phone would give you much more functionality!
 
@OzzieGeorge is so correct with that accessment. Other than maybe a cheap phone and I hope you bought them cheap. The NEC sip phones are worthless as Standard SIP phones.
