Note

If the ANI is not in the database, the gateway prompts the user for an account number or Personal Identification Number (PIN) and sends this number to the RADIUS server for verification.

The steps illustrated in Figure 6-9 are as follows:

4. The user enters the destination phone number.

5. The gateway consults the gatekeeper on ways he can route the call.

6. The gatekeeper looks up the E.164 address against a table and sends the gateway the IP address of the destination gateway.
