Description

The Grandstream GXW-4104 offers an easy to manage, easy to configure IP communications solution for any small business or businesses with virtual and/or branch locations who want to leverage their broadband network and/or add new IP Technology to their current phone system. The Grandstream Enterprise Analog VoIP Gateway GXW410x series converts SIP/RTP IP calls to traditional PSTN calls. There are two models – the GXW4104 and GXW4108, which have either 4 and 8 FXO ports respectively.

Grandstream GXW-4104 Features

• 4 ports
• 2 10/100 Mbps network ports
• Comprehensive codec support, caller ID, flexible dial plans and security protection
• Advanced security protection with SRTP

The installation is the same for either model. A SIP proxy server such as Asterisk or a SIP registrar server can be deployed with the GXW-4104 series. In this environment, the SIP server handles SIP registration and call control and the GXW-4104 processes media conversion between IP and PSTN calls. By design, the system supports the North American call progress tones and signaling standards on PSTN sides.
