We are looking into building an Asterisk <a href="https://www.asterisk.org/">https://www.asterisk.org/</a> PBX, and I was wondering if I would be able to salvage our Nitsuko phones.

The bottom of the phone says:
Code
Nitsuko 124i/384i
128 HF W/SK DISP
Part # 92753 HAC
66113098 JK
DX2NA-12CTXH TEL (BK)

Do the phones follow some standard, or will I have to throw them away?
