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.

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.
