stop-only—The voice gateway sends an Accounting_Stop request to the RADIUS server only
when the call ends, and it releases the call only after receiving an Accounting_Stop
acknowledgment.
Voice dialing process
There are two types of dialing process for voice calls: one-stage dialing and two-stage dialing.
Two-stage dialing consists of caller number process, caller number process with IVR, and card
number/password process.
1. One-stage dialing—The calling party directly dials a called number. The RADIUS server
performs authentication for the calling party, authorization for the called party, and accounting
according to the AAA configuration for one-stage dialing process.
2. Two-stage dialing—The calling party first needs to dial an access number and then a called
number. The RADIUS server performs different AAA operations for different access numbers:
Caller number process—The calling party first dials an access number, and after hearing
a dial tone, dials a called number. The voice gateway originates a call according to the
called number.
Caller number process with IVR—The calling party first dials an access number. The
voice gateway plays a prompt tone. The calling party performs operations as prompted, and
then dials a called number. The voice gateway originates a call according to the called
number.
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 might 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.
