One way: write a simple python script,
```import random
phone_numbers = []
with open(&#x27;list_of_phone_numbers.txt&#x27;, &#x27;r+&#x27;) as file:
   for phone_number in file:
       phone_numbers.append(phone_number)<p>random_pick = random.randint(0, len(phone_numbers)-1)
print phone_numbers[random_pick]```
