RE: T48G Problems with old Plantronics Headset
What is your old phone? Pinout is almost certainly different. If you know the wiring of the old phone you can figure out what is mic and what is speaker, then re-arrange and re-terminate (or get a new compatibility cord) accordingly. Yealink needs the U10P-S cord I believe.
