Radius Provided By Voice Gateway - 3Com MSR 50 Series Configuration Manual

RADIUS Provided by
Voice Gateway
1 One-stage dialing: The calling party directly dials a called number. The RADIUS
2 Two-stage dialing: The calling party first needs to dial an access number and then
message exchange in the entire process is quite complicated, access
procedures differ, AAA fails, calls are exceptionally terminated, or the called
party hangs up.
Obviously, RADIUS cannot operate normally without the RADIUS server. AAA
messages exchanged between the voice gateway and the RADIUS server should
comply with RFC 2865 and RFC 2866. A list of voice call users of the voice
gateway should also be configured on the RADIUS server.
AAA for voice calls
For voice calls, the RADIUS authentication includes card number/password
authentication and calling number authentication, and the RADIUS authorization
adopts the called number authorization mode on condition that the RADIUS
authentication is enabled.
For voice calls, the voice gateway supports three accounting methods: start-ack,
start-no-ack, and stop-only.
start-ack: The voice gateway sends an Accounting_Start request to the
■
RADIUS server and needs to receive an Accounting_Start acknowledgment
before connecting a call. The voice gateway sends an Accounting_Stop request
to the RADIUS server but does not need to receive an Accounting_Stop
acknowledgment before releasing the call.
start-no-ack: The voice gateway sends an Accounting_Start request or
■
Accounting_Stop request to the RADIUS server before connecting or releasing
a call, and directly connects or releases the call without waiting for an
acknowledgment from the RADIUS server.
stop-only: The voice gateway sends an Accounting_Stop request to the
■
RADIUS server before releasing a call, and directly releases the call without
waiting for an acknowledgment from the RADIUS server.
Voice dialing process
There are two types of dialing process for voice calls: one-stage dialing and
two-stage dialing. Two-stage dialing falls into caller number process, caller number
process with interactive voice response (IVR), and card number/password process.
server performs authentication for the calling party, authorization for the called
party, and accounting according to the AAA configuration for one-stage dialing
process.
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.
