I am attempting to use a Plantronics HW261N headset with the OBI 1032 phone via the 3.5mm jack. This headset worked flawlessly with my old Polycom phone, but with the OBI 1032 I am hearing lots of buzzing and a very bad echo. I have played around with all of the Preference settings for echo, volume, and mic gain but none seem to have any affect. I have run out of things to try. Any help would be appreciated.
That's a very old headset. You'll get much better results using a modern, USB-attached (digital interface) headset. Most USB headsets should work fine, with no interference/buzzing/hum
Well, it is one of the headsets recommended for use with the 1032.

Its simply a wired headset. There really shouldn't be any problem. It works fine on all other phones except the OBIHAI.
Here is a follow-up for anyone with the same issue. The HW261N has a Quick Disconnect connector. I originally ordered a QD to 3.5mm adapter, without checking to see if I needed TRS or TRRS (the pin configuration). Although I couldn't find a reference anywhere on the OBIHAI site, I can tell you that you need the TRRS style 3.5mm connector. Once I tried the correct one, everything worked fine.
