I need to build an adapter cable with a RJ9 handset plug on one end and a 2.5mm headset plug on the other.
Long story... Our ATT 972's have a 2.5mm headphone jack but the signal is too weak for a mobile phone headset. Ergo, we need to use headsets with amplifiers and they only accept a RJ9 input.
Can someone post wiring diagrams for standard RJ9 handset plugs and 2.5mm headset plugs? With that info, I'll be able to build the adapters.
...thanks
