How can we connect a secondary handset or telephone ?
On the power bloc we juste have a RCA connector in middle, we don't have the DATA connector as it's written on the manual.

Polycom manufactures multiple local versions of our Phones and most likely the region you are using the phone in does not have this feature.
The guides are often general guides covering the global versions of the hardware.
