other at the network layer, and that a list of one-stage dialing users as well as authorization policies has
been configured on the RADIUS server.
Configuration prerequisites
A voice interface card (for example, an FXS interface card) is inserted in the router.
The authentication function is enabled for one-stage dialing users. Authentication is a prerequisite for
authorization. The authentication function must be enabled before the authorization function. If the
authentication function is not enabled for one-stage dialing users, the authorization-did command is
unavailable. If the authentication function is disabled, the authorization function will automatically be
disabled.
Configuration procedure
To enable the authorization function for one-stage dialing users:

authorization-did Disabled by default.
NOTE:
Consecutive authorizations except the first one performed within the authentication time limit will fail, if the
number of online users is limited to 1 for an account in the RADIUS server. This rule applies to one-sta

dialing users and two-stage dialing users.
Configuring rule for saving CDRs
Each time a call is terminated, a CDR is generated in the following two cases, no matter whether the call
is connected:
• Any of the authentication, authorization, and accounting functions is enabled for calls originated
from the local voice gateway.
• The accounting function is enabled for incoming calls of the local voice gateway.
In view of the limited memory of the voice gateway, only a limited number of CDRs can be saved.
Therefore, you can set a limit on saved CDRs. There are two ways to limit CDRs saved in the voice
gateway: limit the number of CDRs, or limit the lifetime of CDRs. You can also set a CDR alarm threshold.
At most 500 CDRs can be saved in a voice gateway. That is to say, the number of CDRs saved in the
voice gateway cannot exceed 500 even if none of the saved CDRs in the voice gateway has reached the
lifetime. In the case that bursty traffic is generated during a period of time, the CDRs for the calls
completed earliest are removed to keep the number of saved CDRs under 500 even if they have not
reached the lifetime.
