The Multi-Service Business Gateway (MSGB) is a new form of router that will be used in SMBs and enterprise branch offices to replace standalone PBXs, Internet Access Devices, Firewalls, and Routers with a single device. MSBGs built on a router platform will allow service providers to offer new applications and services for SMBs and give the enterprise the capability of extending headquarters-level voice and data services to branch offices.
The market for MSBGs is just now beginning to emerge as manufacturers introduce router-based appliances and develop their marketing channels. However, the market will take a slow growth path as vendors run up against a large amount of installed voice and data infrastructure that is in-place and serving customer needs.
Readers will find a discussion of why vendors are shifting away from telephony/PBX-based appliances to router-based products using IP for voice and data transport, and the new services and application opportunities that will emerge as a result of the combination of MSBG and IP.
