ONFIGURATION
Card number/password process: The calling party first dials an access number.
■
The voice gateway plays a prompt tone. The calling party enters a card number
and password as prompted, and then dials a called number. The voice gateway
originates a call according to the called number.
The RADIUS server needs to obtain the caller's identity information, which may be
the calling number or the preset card number and password, before performing
AAA operations for a voice call. The voice gateway uses the collected calling
number or card number and password to originate an authentication request to
the RADIUS server, and determines whether call origination is allowed according
to the returned result.
The AAA function for one-stage dialing process applies to all one-stage dialing
users. For two-stage dialing users, you can configure different access numbers. For
these access numbers, you can configure different AAA schemes and different
two-stage dialing attribute parameters (for example, redial attempts and number
of digits in a card number/password). In addition, you can customize the detailed
access procedure according to the specific requirements. For example, you can set
these access numbers as private line auto ring-down (PLAR) numbers on voice
subscriber lines to implement the auto-dialing of access numbers.
If a voice call is originated from an IP network, the voice gateway does not
■
support the direct dialing of access numbers, and for one-stage dialing, it
supports only accounting, instead of authentication and authorization.
The voice gateway does not support the nested dialing of access numbers. That
■
is, a user cannot dial an access number again after dialing it during a call
originated from or terminated to a voice gateway.
Voice prompt
Voice prompts in Chinese and English are available in the card number/password
process and caller number process with IVR.
Recording and querying detailed voice call information
This function records detailed information of each voice call. You can 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.
