Hello. basically ive got spark Fibre - & Everything is going except ive not got my phone connected.

Ive found instructions to say insert the phone jack intothe PHONe1 jackpoint in the modem. 

However my phone cord/jack doesnt fit into that slot in the modem.

I am wondering if theres a good video or whatever to show where to connect the wires (just for the phone).... Am i trying to connect to the correct place ?
