7The externpasscheck option in voicemail.conf allows an external script to
8validate passwords when a user is changing it. The script can enforce password
9strength rules. This script is an example of doing so and implements a check
10on password length, a password with too many identical consecutive numbers, or
11a password made up of sequential digits.
