I have a Plantronics H-Series headset with the 2-prong adapter i want to adapt to a CDM1550LS. The 2 prong adapter has a volume control on it, and I understand the mic is on the tips and the earphone is on the rings, but does anyone know how i power this thing? thanks

The 2-prong adapter is a "PJ 327 Plug Prong interface" - We use one with a CDM wired through an interface box. The number on the box is BLNT6223A-CS-5. From what I understand, the box is from a Centracom Console.

It should be self powered from the mic bias line.
