FROM HDZHANG1987E ERA: Ringing the alarm on an IFE METIS-CR

Newer IFE lifts since 2016 have an autocall feature enabled whereby pressing the alarm button WILL lead to connection attempts. This can be heard from the telephone ringing sound when the alarm button is pressed down. However, after the ringing sound there is no response as it is probably not connected to EMSU's number.

I have never gotten stuck in an IFE before but hope to do so because I want to try out that feature.
