[asterisk-users] User-invoked call restrictions

[David A. Bandel]

Folks,

Had a request from a customer:  is it possible for a customer, using a
password to restrict others from making long distance/cell calls?
That is, the user set a level of service?

Something like this:
Customer dials a number -- "operator" asks for password, then service
level (another number).  Service level would be something like:
1 - allow inbound calls only
2 - allow 1 + local/toll free calls
3 - allow 2 + long distance national
4 - allow 3 + cell calls
0 - allow 4 + international calls (basically cancel all call restrictions)

Dialing to restricted zones would evoke a message from the operator
that the phone is blocked by owner.

Code examples?  Hints?  RTFM URL?

TIA,

David A. Bandel
