DNIS authorization

Dialed Number Identification Service (DNIS) enables authorization of a connection attempt based on the number called. DNIS identifies the number that was called to the receiver of the call and is provided by most standard telephone companies. For example, you could allow all connections that connect through a specific toll-free number. To identify DNIS-based connections and apply the appropriate connection settings, you must do the following:

  1. Enable unauthenticated access on the remote access server. For more information, see Enable authentication protocols.

  2. Create a remote access policy on the authenticating server (remote access server or IAS server) for DNIS-based authorization with the Called-Station-Id condition set to the phone number. For more information, see Introduction to remote access policies and Add a remote access policy.

  3. Enable unauthenticated access on the remote access policy for DNIS-based authorization. For more information, see Configure authentication.

Notes

  • If your phone service or hardware does not support DNIS, the passing of the number that was called, you can manually set the phone number of the port. For more information, see Set the phone number on a port.

  • IAS does not support proxied DNIS access requests.
