sopho engaged light 1

[ssuem118]

We would need to install a light/led over one of our communication posts, to see when one person is engaged at the telephone.
How it’s possible to make it?
On the behind of the phone is present a door, a model with 9 poles; it’s possible to have an electrical pattern, or use it to connect it to a led?
Thank you

An RJ11 socket on the base of the ErgoLine D340 can be used as an external control line for
items such as a second bell, a door opener or a door lamp. A single input channel for footswitch
operation is also available.

1 +5V supply voltage
2 Busy indication
3 Door opener

5 Earth
6 Second bell

I thank COOLDUDE6 for the answer.

On the base of the telephone I have three takings RJ11; the first one is the exit for the cornet and the bonnets, the second it brings the writing "audio", the third one the symbol of an switch, that I think both that to be used for connecting the leds.

I have tried the connections among the pin 1-2 and 2-5, but the led remains always turned on, both in attended that during a phone call.
Must the telephone be programmed perhaps?

Can someone tell me to which pin it is correct to connect the leds?

Thanks
