Product Description
The Grandstream GXW-4108 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-4108 Features
- 8 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-4108 series. In this environment, the SIP server handles SIP registration and call control and the GXW4108 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.
