While this has increased Internet Protocol Private Branch Exchange (IP PBX) deployments, Time Division Multiplexing (TDM) infrastructure is, however, still prevalent, warranting media gateways to bridge the two technologies. Realizing the potential opportunities, gateway vendors are enhancing their offerings to provide more reliable and secure solutions to end users, helping them meet the challenges of hybrid environments.
New analysis from Frost & Sullivan (enterprisecommunications.frost.com), World Enterprise Media Gateway Markets, reveals that revenues in this market totaled $1.17 billion in 2006, and is likely to reach $2.39 billion in 2012.

“The transition to an IP-based world is at least 20 years away and the move from TDM to IP-based voice communications will require a long period of co-existence of both technologies until all equipment are replaced,” notes Frost & Sullivan Research Analyst Laura Devoto. "Gateways that convert one protocol to another will hence be absolutely essential to ensure the integration and smooth functioning of TDM-IP hybrid networks in the mean time.”
While gateways were initially deployed to take advantage of the cost reduction associated with toll bypass, they are currently being deployed by enterprises interested in obtaining the enhanced benefits of IP PBXs or wanting to deploy VoIP services without replacing their existing TDM infrastructure. Additionally, branch office solutions have been gaining traction as businesses seek to give all employees access to IP telephony features residing on a central server.
Other applications deploying enterprise media gateways include IP PBXs connecting to the Public Switched Telephone Network (PSTN) and VoIP access lines connecting to legacy equipment at the enterprise. These two scenarios are likely to grow in importance as the penetration of IP PBXs increases and VoIP access services become more widely available.
Nevertheless, some enterprises are still reluctant to trust their voice communications to IP networks mainly due to reliability, quality of service, and security concerns. They expect the IP network to grant them the same quality service that the PSTN offers. Therefore, they have been slow in adopting VoIP services and IP telephony solutions and this has acted as both a driver and a restraint for the deployment of media gateways.
“Quality of service, reliability, and security are major concerns among enterprise customers, deterring them from deploying VoIP on a large basis”, explains Devoto. “Furthermore, the fact that small enterprises have limited IT budgets and might be tempted to deploy lower-quality consumer VoIP products and services has negatively impacted their perception of next-generation technologies. Moreover, interoperability issues present additional hurdles for customers seeking to deploy islands of VoIP within predominantly TDM environments”
Given these challenges, it is imperative for gateway vendors to provide highly reliable, redundant, and secure solutions to secure a competitive position in the marketplace. Besides, it is crucial for stand-alone gateway vendors to offer extensive interoperability and ease of management, as these are additional obstacles for them, in a market where complete solution providers such as Cisco and Avaya have a head start over them.
