you have supply power to them

you have to supply power to the side card through a power cube and connect it up  with an AUX lead to the main phone.Check overview section here for the compatibility and here is a good thread about configuration

Hi Maussa,

Hi Maussa,

To make is simpler:

1 IP phone  with POE + 1 7915 module = need power adapter

1 IP phone  with local power + 1 7915 module =no additional power cube.

1 IP phone  with POE or local + 2 7915 module = Definitely need power cube
