Understanding VoIP Gateways

A gateway for VoIP, otherwise known as Voice over Internet Protocol gateway is a component that transforms analog telephony signals to digital signals. The gateway is a type of hardware that has been designed to transform TDM telephony traffic from the PSTN into digital  IP packets for transport over to an IP network. A type of IP network that can receive this packet can be a LAN network, though there are many others. The VoIP portal can also transform digital IP packages into traffic known as TDM telephony. This type of connection is used for transportation across the publicly switched telephone network, which is otherwise known as the PSTN. For more detailed information on the voice over internet protocol, read the article below.
The method in which a VoIP gateway can function is simple. A voice over internet protocol portal functions as an overpass that is placed in between the publicly switched telephone network and the IP network. The voice over internet protocol, depending on the origin location of the voice traffic, will then transform the voice traffic into a standard mold that fits its destination network, which can be either the publicly switched telephone network or the IP.
In the case that the voice traffic stems from the publicly switched telephone network, the voice over internet protocol will enable the transformation from an analog voice signal into a digital signal. That digital signal is then compressed by way of a codec and is then categorized into a line of packages that can be taken with a signaling protocol and moved throughout the IP network. If the voice traffic is originating from an IP network the voice over internet protocol gateway will decompress the digital packets into a digital signal that is then converted into an analog signal to be sent across the publicly switched telephone network.
If you are working on your internet gateway, you need to use the codec and the protocol so as to ensure that the portal is working correctly. Not only that, but you must ensure that the codec is suitable for your voice over internet protocol phone system or other systems. Depending what kind of codec or protocol you use, you can significantly strengthen or weaken the quality and standards of your call.
When it comes to the protocol for the voice over internet transfer, it is the VoIP that is the determining factor of how your voice packet is taken throughout the network. Normally, a voice over internet protocol portal will maintain just one protocol.
There are various voice over internet protocols, but the most common types include but are not limited to the SIP, which is the Session Initiation Protocol, the SCCP which is the Skinny Cisco Client Control Protocol, the MGCP, and the H.323. The SIP refers to a\ standards-based protocol that is utilized and supported by the overall majority of VoIP phone systems while the SCCP is a proprietary protocol used by Cisco's as well as other IP phones. Meanwhile the MGCP refers to an older voice over internet protocol that is no longer supported, while the H.323, much like the former, is an older voice over internet protocol that is generally obsolete.
