Due to ongoing issues with my landline since getting fibre I need to disconnect my security alarm from the phone line.

The security guy says  "The best way to disconnect the monitoring is to join the IN and OUT wiring together in the control panel, as this will eliminate the alarm system from the phone line all together!"

The above is a photo of two wire blocks with TELCO LINE written underneath. I presume one is IN and one is OUT and it matters not which is which.

What I need to know is do I join...

(white1 - white2) and (brown - blue)?

or...

(white2 - blue) and (white1 to brown)?

or...

(white1 - blue) and (white2 - brown)?

To actually do the joining, I unscrew each wire from the block then just twisty them together in mid-air?

Any help greatly appreciated.
