A VoIP gateway is a piece of hardware with the standard purpose of converting TDM telephony traffic from the PSTN(for example like mtnl, airtel,tata etc) into IP packets for transport over an IP network (such as your LAN). A VoIP gateway can also convert digital IP packets into TDM telephony traffic for transport across the PSTN (Publicly Switched Telephone Network).. They are used in 2 ways:
In this manner the VoIP gateway allows calls to be received & placed on the regular telephony network (MTNL, AIRTEL etc) . In many business cases, it is preferable to continue to use traditional phone lines because one can guarantee a higher call quality and availability.
In this manner the VoIP gateway allows calls to be made via VoIP. Calls can then be placed via a VoIP service provider, or in the case of a company with multiple offices, inter office calls costs can be reduced by routing the calls via the Internet. VoIP gateways are available as external units or as PCI cards. The vast majority of devices are external units. A VoIP gateway will have a connector for the IP network and one or more ports to connect the phone lines to it.
VoIP gateways are rather simple. VoIP gateways are a type of VoIP equipment that uses VoIP technology to convert analog voice streams to digital voice packets.
A VoIP gateway works as a bridge between an IP network and the PSTN.
If the voice traffic is originating from the PSTN the VoIP gateway will convert the analog voice into a IP.
If the voice traffic is originating from an IP network the VoIP gateway will convert IP into an analog signal to be sent across the PSTN.
