Plantronics headset to normal phone converter.

I need help trying to "hack" a Plantronics headset with a quickdisconnect connector to work on a "regular" phone.

I have a plantronics headset but I'd like to use it with my phone.
I ripped apart the wire that had the quickdisconnect (http://www.headsetsdirect.com/knowledge_base/hd_6000_plxqdn.jpg) connector to expose the 4 wires. They are red, black, green and white.
I opened the headset to see the place where they connect, labeled as such:
Red = RX-
Black = TX+
Green = RX+
White = TX-

I connected RED and GREEN to the connector which plugs into the mini connector for the handset on the phone, and was able to get the speaker working, however I cannot get the microphone working with the two wires that are left.

Does anyone have any ideas of what I could try?
Any help will be appreciated!

Well, RX typically means receive, so that would explain why it got your speaker working, TX would be transmit, so it should just be Black for TX positive, and White for TX ground. Thing of it is, if it's an office style headset, they are frequently used with amplifiers which allow you to control the amount of volume you are sending to the person on the other end of the call, so you may need to increase the voltage somehow.

I hope you get an answer, I would love to know how to do this as well.

On a normal telephone handset connector,

Red is MIC-
Black is SPK+
Green is MIC+
White/Yellow is SPK-

If your microphone is not working, try reversing the polarity of those contacts (though it shouldn't matter). Most likely, the Plantronics mic requires powering, and the phone is not powering the microphone.

If you have any other electronics laying around with an old mic in it (for example, your scrap phone handset) take the microphone from it and connect it to the two remaining pins. If it works, but doesn't work with your headset, you know it's a power issue and you just need to replace the tiny mic element in the headset with something that doesn't require power.
