AHA!

There was that voice with the greeting! What next? Adi glanced down at the paper. He had never recorded a voice mail greeting for himself except on his cellphone and that method had been different. He punched at the numeral four button. After a few seconds of listening, the Hufflepuff pushed at the numeral one button this time. The voice informed him something about recording his greeting after the beep. Yada, yada, yada.

A beep. He need to wait for a beep. He rested his right ankle on his left knee, jangling the said ankle as he waited for that beep.
