Citel’s Handset Gateways enable small and medium-sized businesses, as well as large enterprises, to take advantage of feature-rich IP Centrex or SIP-based IP PBX services while still retaining their existing desktop handsets, wiring infrastructure, and data network. Existing business grade PBX handsets connect directly to the Citel Handset Gateway through existing wiring, which connects to an Internet Telephony Service Provider (ITSP) or IP PBX over Ethernet via the SIP protocol. Citel’s Handset Gateways interoperate with a wide variety of digital PBX handsets and robust IP application servers.
Citel’s Handset Gateway products allow enterprises to keep digital PBX handsets already installed and in place, migrating to a new, feature-rich IP PBX, all at a fraction of the cost of an entirely new IP PBX and IP handsets. Or, enterprises can mix and match new IP handsets with legacy handsets as they see fit.
Enterprises obtain all the economic, productivity and feature benefits of VoIP, for significantly less CAPEX investment than other VoIP systems.
