Something really cool in Asterisk - This is something an organization with LARGE number of users can use. You can now, get Asterisk to interface with AD or any applications, and get your users to reset passwords via the IVR. This means, the guys and girls at the help desk can concentrate in doing what they are paid for.
Well this solution is both secured and reliable. We have 2 customers that loved this solution. One is from the O&G industry and the other is from a Financial industry.
Imagine this .. you have an average of 2000 calls per month on password resets. Now all of such request can be handled by the IVR via Asterisk. Kewl no?
