VOIP Business GSM Gateway

Make Calls Over the Internet With a VoIP GSM Gateway

A VoIP GSM Gateway allows you to bypass standard telecom networks entirely and make calls over the internet. This can make calling more affordable for both homes and businesses, but you'll need the gateway device in order to make calls over the Internet. eBay has a huge selection of VoIP GSM Gateway devices for you to choose from.

A VoIP GSM Gateway is a device that connects a VoIP (or Voice over IP) network to a GSM network. VoIP networks are protocols and sets of technologies that are meant to transmit voice communications over the internet or other sorts of IP networks. VoIP can also handle the transmission of other multimedia information. GSM networks are basically just cell phone networks. Essentially, a VoIP GSM Gateway allows you to connect the internet to a telecom network, enabling you to transmit calls over the internet instead of through a standard telecom provider and its network.

If you run a company where employees are required to make a tremendous amount of calls every day, such as a call center, then you'll know that you'll end up paying a great deal in fees to a telecom provider in order to use that provider's network infrastructure. A VoIP GSM Gateway, however, allows you to cut out the middleman and place outgoing calls at intranet rates, which are typically much lower than telecom rates. If you do a lot of international calling at home, you might also benefit from a VoIP GSM Gateway that could keep you from paying expensive international calling rates.

Although there is some variation to be found between the different available models of gateways, broadly speaking, they generally have features like the following:

• Support: You usually have support for Open Standard VoIP Protocols of some kind, such as ITU H.323 V4 and IETF SIP V2.
• Ethernet ports: There are ethernet ports so that you can connect the device to other devices or to your Local Area Network.
• GSM module: A GSM module makes it so that you can make GSM calls.
• SIM card slots: There are also slots you can insert SIM cards (generally 16) in, which are necessary to connect the gateway to the requisite network.
• Router: The router makes it so you can connect to the internet wirelessly.
• Buffers: There are built-in ways to ensure sound quality, such as by QoS at the Ethernet and IP layers and a jitter buffer.
• Processor: You'll also find a processor like the ARM 9, which allows the gateway to run an operating system (generally Linux) though which it can perform its operations.
