Hi,
I have some 2565 6-button business phones in corresponding 4A speaker phone setups using 82-type connecting blocks, and they works perfectly with a 620 panel. I just tried to substitute a 2563HBMS set with a headset jack for one of the 2565s, and it wouldn't work at all -- everything was completely dead.
I checked Section 512-700-100 of the BSP, and it didn't specify that the 4A speaker phone wasn't designed to work with a 2563 set. Section 502-543-400 of the BSP, which deals with 2563HB sets, doesn't mention that the 2563 set wasn't designed to work with a 4A speaker phone, but the diagram of the 2563 doesn't include any of the leads normally used with a 4A speaker phone, e.g., no TI, RI, IT, AG or LK leads are shown on the 2563 diagram.
Am I correct in assuming that the 2563 set will not work in conjunction with the 4A speaker phone?
Thanks, Bill
