What is Media Gateway Approval?
Media gateway approval is an authorization to set up a media gateway – a translation device used to convert media streams between different telecom networks.
A media gateway is a translation device. It converts multimedia data streams to transmit them through dissimilar telecommunication networks. The concept of such a gateway originated as a TDM-based voice network that uses IP for voice transmission.
Now, it has evolved into a device that converts voice and other multimedia data streams across a wide variety of service provider applications and enterprise applications.
Following is how media gateway assists enterprise applications:
- SIP Trunking services to legal PBX equipment.
- Connection of legacy infrastructure to new IP-based cores.
- Protection and extension of the previous TDM.
- Preservation of existing line equipment.
- Preventing expensive rip and replace upgrades.
Following is how media gateways assist service provider applications:
- Facilitating interconnection and joint operation for CDMA, GSM UMTS and satellite networks in 2G, 3G, 4G, and future 5G architectures.
- Enabling IP media processing for IP MSA networks
- Providing facility to interconnect and jointly operate the Class 4/ IP tandem/ IP trunking and Class 5/subscriber.
- Conducting IP to IP media conversions for interconnected networks
However, setting up a media gateway is not a simple technical task. There are legal aspects to it as well. Department of Telecommunication has to give its approval before you can set up a media gateway as a service provider. That approval is known as the media gateway approval.
