POTS network is omnipresent. GSM networks are well-liked with the inherent extensive coverage. IP telephony promises to be the preferred communication technology for future. Not all businesses are equipped with telecom infrastructure flexible enough to access these multiple networks. On the other hand replacing their existing telephony can be a costly affair. For instance, an organization with POTS communication backbone, needs connectivity to VoIP and GSM networks or a business communicating through IP based platform, needs to connect to GSM and POTS network. Under such circumstances a solution that offers connectivity to these networks using existing communication infrastructure, is the need of the hour for any business. The gateway can then dynamically select between the networks and offer better QoS (Quality of Service), convenience and cost benefit.

VoIP-GSM-FXO-FXS Gateway
Introduction
SETU VGFX is a Single-box gateway solution, offering seamless connectivity between VoIP, GSM and POTS (FXO and FXS) networks. The multi-port configuration, offering 4 GSM, 4 FXO, 4 FXS, up to 8 simultaneous VoIP channels and support for multiple SIP trunks, makes SETU VGFX the ideal stand-alone gateway for SOHOs. At the same time, it can be interfaced to existing (traditional or IP) infrastructure. The support for open-standard SIP protocol ensures interoperability with existing IP infrastructure. On the POTS side, both FXS and/or FXO interfaces are supported. On the GSM side, it supports Quad-Band GSM operation, allowing it to work with any GSM network
Using SETU VGFX, a traditional PBX system can enhance its capability and connect to VoIP and GSM networks. SETU VGFX can be connected to a traditional PBX in two ways. Firstly, the FXS ports of SETU VGFX can be connected to the FXO ports of the PBX. On dialing prefix assigned in the PBX, the user can access these FXS ports to make GSM or VoIP calls. Secondly, the FXS port (SLT port) of the PBX can be connected to FXO port of the SETU VGFX. PBX users can access VoIP and GSM network connected to SETU VGFX by dialing the FXS port number of the PBX.
SETU VGFX enables the IP PBX users to make calls to the GSM and POTS network. It assures users the most cost effective route of IP for all their calls to GSM and POTS till the last mile of termination. Peer-to-peer calls eliminate the role of IP PBX or SIP proxy server to establish calls over internet. It facilitates easy and low-cost communication between geographically spread, multi-branch offices. The user can access the GSM and POTS facilities of the remote branch office to make calls and save long distance call charges borne otherwise.
With new networks being integrated, communication happens using the most cost-effective networks. Features like Automatic Number Translation, Programmable Access Codes and host of other advanced functionality, enable users to access new networks without changing their dialing habits.

The Stand-alone VoIP-GSM-FXO-FXS Gateway
Matrix SETU VGFX is a single-box solution for Small Office/Home Office, which needs to access VoIP, GSM and POTS networks. SETU VGFX can be configured in a stand-alone mode by connecting standard telephone instruments to its FXS ports and VoIP-GSM-FXO networks to its respective network ports. Calls over IP are made either through peer-to-peer or using the Proxy Server of a SIP service provider. Additionally, FXS to FXS calls can also be placed. Ideal to be used as a stand-alone gateway, SETU VGFX ensures the most cost-effective route for communication.Peer-to-peer calls eliminate the role of IP-PBX or SIP proxy server to establish calls over internet.
