112 is a part of the GSM standard and all GSM-compatible telephone handsets are able to dial 112 even when locked or, in some countries, with no SIM card present. It is also the common emergency number in India and in nearly all member states of the European Union as well as several other countries of Europe and the world.

You can dial it in the US too..

even for 112? what if some real emergency happens (fire/robber/terrorism)? The caller has to listen to the recording?

That's lame.

I wonder if anyone in Turkey is dialling 112 to test if the message is played. Maybe people are calling their mums to test if the message is on, perhaps it is a good day for telco revenue.
