Project Startup

Hello, I am trying to know which Arduino products i should get for my project, I am trying to build up a fall detector that sends a voice call to a relative when the fall happens. I think i should go for the Arduino Esplora given it has a built in microphone and accelerometer, but I am not sure if it can be connected to the Arduino GSM shield for the communication purpose. If not, is there anyting simpler I can do? Thank you
