Executive Summary
While the line between softswitching and media gateways is becoming increasingly difficult to
discern as more vendors blend their products and features into “solutions,” this Report focuses
primarily on the Public Switched Telephone Network (PSTN)-to-packet media gateway market,
which, for purposes of simplicity, we refer to as “media gateways.” Additionally, within this
Report, the Yankee Group divides the media gateway market into four distinct market segments.
However, the fundamental definition of a media gateway remains consistent throughout, as all
media gateways are devices that:
? Reside in a carrier or service provider central office and comply with carrier-class
requirements, such as NEBS Level 3 compliance (enterprise gateways and voice-enabled
integrated access devices are not included in our analysis of media gateways);
? Provide a migration path from a circuit-switched telephony network to a data-centric
network that supports packetized voice switching;
? Can interface with the SS7 network; and
? Are open, standards-based, and can interoperate with the call control and application
elements of partner vendors.
