    What is a VoIP Gateway?

    A VOIP gateway is a device which converts telephony traffic into IP for transmission over a data network. VOIP gateways are available as external units or as PCI cards. VoIP gateways act as VoIP network translators and mediators.

    VoIP gateway comes with the ability to support at least two T1/E1 digital channels. Most VoIP gateways feature at least one Ethernet and telephone port. Controlling a gateway can be done with the help of the various protocols like MGCP, SIP or LTP. VoIP gateways can also help direct VoIP calls to specific users with the assistance of built-in routing tables.




    Types of VOIP gateways
    1. Analog units: Analog units are used to connect regular analog phone lines to it. Analog units are available for between 2-24 lines.

    2. Digital units: Digital units allow you to connect digital lines either one or more BRI ISDN lines (Europe), one or more PRI/E1 lines (europe) or one or more T1 lines (USA).


    Benefits of VoIP Gateways
    The main advantage of VoIP gateway is that it can provide connection with your existing telephone and fax machines through the traditional telephone networks, PBXs, and key systems. This makes the process of making calls over the IP network familiar to VoIP customers.

    VoIP gateways can end a call from the telephone and can provide user admission control using IVR (Interactive Voice Response) system and provide accounting records for the call. Gateways also help direct outbound calls to a specific destination, or can end the call from another gateway and send the call to the PSTN.

    VoIP gateways plays a major role in enhancing carrier services and also supports the simplicity of the telephone calls for less cost and easy access. Flexible call integration has been developed at less cost which enables programmable call progress tones and distinctive ring tones.

    The software is standards compliant and can be used for building both FXS-only Analog Telephone Adapters as well as FXS/FXO gateways and FoIP gateways targeted towards SOHO and Residential markets. HelloGateway has been proven on different hardware platforms and operating systems and tested for interoperability with different SIP based PSTN gateways and FoIP gateways.


    VOIP gateway manufacturers
    There are lots of VOIP gateways available today, and as demand has increased drastically, prices have decreased considerably. Analog VOIP gateways start at as little as $200. Here are a few VOIP gateway manufacturers:

    Functions of VoIP Gateways

    The main functions of VoIP gateways include voice and fax compression or decompression, control signaling, call routing, and packetization. VoIP gateways are also power packed with additional features such as interfaces to external controllers like Gatekeepers or Softswitches, network management systems, and billing systems.


    The Essential Guide to VoIP Gateways

    VoIP gateway serves a very practical purpose. It is a network device that converts voice and fax calls into digital packets — and vice versa — in real time, between the traditional PSTN (public switched telephone network) and an IP network. These packets are compatible with a company’s VoIP system. By performing functions such as voice and fax compression, decompression, packetization, call routing and control signaling, a VoIP gateway enables the data infrastructure to handle voice and other applications. Without a proper gateway, users on a VoIP network cannot make or receive calls to and from outsiders using traditional phone lines.
