She is pressing "2", which turns off the notification. If you (read: they) are using a cellphone without a headset or speaker, you typically can't get the phone to your ear in time to hear the instructions saying "press 1". You will hear "press 2", however and, if someone isn't familiar with the system, they'll go ahead and "press 2" like the nice lady told them to.
I had this set-up with an (older) group of doctor's = pulling hair out of my head trying to train them.
