After talking to a few headset companies they just stated I needed a headset system with a Amplifier. So we have started with trying the Plantronics S12 System, and now we are getting a Plantronics CS361N Headset for wireless.
The catch here is that you will head a headset lifter if you don't want to have to be at the desk and lift it up for each call.
It should also be noted that there aren't any guarentee's. Plantronics said that the S12 should work but wouldn't say for sure as they didn't have any info on the DPH-125MS. It is a bit of hit or miss but i can vouch for the S12 at this point. We have had one now for about a week and it works great.
