Recording and querying detailed voice call information
This function records detailed information of each voice call. Use the cdr command to set the lifetime and
number of records. The following call information is recorded:
• Calling number.
• Called number.
• Voice port number.
• IP address of the peer voice gateway.
• Call setup time, call-connected time, call release time, and call duration.
• Number of received/sent bytes, and number of received/sent packets.
You can retrieve the call information by calling number, called number, prepaid card number, voice
subscriber line number, and peer IP address.
Voice RADIUS configuration task list
For specific configurations of the RADIUS server involved in voice RADIUS configuration, see Security
Configuration Guide.
When you configure voice RADIUS, pay attention to the sequence and the applicable scope of
configuration tasks.
• The authentication function must be enabled before the authorization function because the former is
a prerequisite for the latter.
• The AAA function differs in the enabling method and application scope between one-stage dialing
users and two-stage dialing users. The one-stage dialing configuration applies to all one-stage
dialing users, while the two-stage dialing configuration applies to only the users who use a specific
access number.
• The setting of the accounting function is independent of the enabling of authentication and
authorization functions, and the accounting function applies to both one-stage dialing users and
two-stage dialing users. Make sure necessary information (including IP address of the voice
gateway, voice port number, calling number, and card number/password) is configured on the
RADIUS server.
Read through the following sections and acquaint yourself with the views, steps, and applicable scope
of all commands.
Voice RADIUS configuration tasks include the following:
• Enter voice AAA client view.
• Configure the accounting method.
• Enable the AAA functions for one-stage dialing users.
• Configure a rule for saving call detail records (CDRs).
• Configure access numbers.
• Configure a two-stage dialing process.
