3.1 Configuration Description
The HG850 supports the VoIP service. When the network is normally connected, the
voice call can be realized after the HG850 successfully registers to the media gateway
controller (MGC) server, for example, the switch.
The HG850 supports the data service. It enables PCs to access the network through the
Lan interfaces.
The HG850 has two software versions: Media Gateway Control Protocol (MGCP) and
Session Initiation Protocol (SIP). Both the two software versions support VoIP services
and data services.
In this chapter, the HG850 serves as a media gateway (MG) and the softswitch device serves
as a MGC.

identifier.
