How to do virtual atendent with caller identification?

Hi guys,

I would like to do something like when you call a Mobile Carrier for example,

The caller will walk throught a menu, like:

"Dial 1, if you cant make a call, dial 2 if you cant recive a call, dial 3 for billing information"

For instance: 1

"Please dial your phone number"

For instance: 555-1234

"Please hold while we transfer your call"

Then the softphone rings with the caller NAME and the respective problem chosen from the list.

How do integrate my clients Data Base to the Asterisk and how do I make it ask for the client NUMBER or Cliente ID, and show the client NAME on the incomming call on X-lite?

Thanks.
