AudioCodes Mediant 8000 - Configuring and Operating the Media Gateway (Part 3)-SIP Subsystem

Part V
Configuring and Operating
the Media Gateway (Part 3)-
SIP Subsystem
This part describes the hardware overview of the Mediant 8000 chassis.
SIP (Session Initiation Protocol) is a standards-based application-layer call control
protocol defined by IETF RFC 3261. SIP is used on the Media Gateway for creating,
modifying, and terminating sessions with one or more participants. These sessions
can include Internet telephone calls, media announcements and conferences.
The Mediant 8000 supports the following SIP applications:

PSTN Gateway – provides gateway functionality between the PSTN and IP
networks

IP-to-IP – provides IP-to-IP call routing functionality

SBC – provides Session Border Controller (SBC) functionality
Each Media Gateway board operates as a stand-alone SIP Media Gateway.
Therefore, the SIP configuration is performed independently for each Media Gateway
board.
SIP subsystem configuration consists of the following categories:

General SIP configuration – applicable to all applications (see page 547)

PSTN Gateway and IP-to-IP configuration – applicable to PSTN Gateway and IP-
to-IP applications (see page
649)

SAS Configuration (see page 715)

SBC configuration – applicable to SBC application (see page 725)
