1 Overview
This document describes the configuration procedures required for a Grandstream GXW4004 / GXW-4008 / HT-502 to make full use of the capabilities of B roadWorks.
The GXW-4004 / GXW-4008 / HT-502 are a few of the many access devices that
interoperate with BroadWorks.
The GXW-4004 / GXW-4008 / HT-502 uses the Session Initiation Protocol (SIP) to
communicate with BroadWorks for call control. It also translates voice to audio packets for
transmission across a packet network.
This guide describes the specific configuration items that are important for use with
BroadWorks. It does not describe the purpose and use of all configuration items on the
GXW-4004 / GXW-4008 / HT-502. For those details, see the GXW-4004 / GXW-4008 / HT-502 User Manual supplied by Grandstream 1.a)i.[1]
