PBXgateway™ I

Extend enterprise PBX functionality to branch offices, call centers, single users, and mobile devices.

Key Features

In enterprises with distributed locations, branch locations and home-based workers often utilize telecom and datacom infrastructure that is far inferior to the headquarters location. The Citel PBXgateway I, deployed with compatible Citel EXTenders, enables off-premise workers with seamless access to the corporate voice network, regardless of geographic location. All employees utilize a single, centralized voice platform, increasing productivity and reducing operational expenditures.

The PBXgateway I terminates the Citel EXTender 4000, 4100, and 6000 series. To deploy a PBXgateway I solution, simply install one or more units within 500 feet of the PBX, and one or more compatible EXTenders at the remote location(s). The PBXgateway I works with most leading PBX platforms and digital handsets over T1, ISDN, Frame Relay, and IP connections. In addition, both PBXgateway I and II support mobile phones through the included MobileConneX software.

The PBXgateway I is available in both 8-and 12-port configurations. It supports several compression rates, allowing the enterprise to select the bect performance for its specific network requirements.sm_PBXgateway

Key Benefits

Increased Productivity

With the PBXgateway I deployed as part of an endto- end Citel VoIP solution, branch office and other remote employees use full-featured digital handsets to access the corporate PBX dial tone, receive calls, and invoke business calling features such as internal dialing, transfer, hold, and conference. The easy system maintenance frees up valuable time and resources for IT and telecom staff.

Cost Savings

Telecommunication costs fall by up to 30% just by administering all PBX users from a single location and platform. And with access to internal (four-digit) dialing, there are no toll charges when calling any office within the enterprise, regardless of physical location. Further, placing regular long-distance and international calls through the corporate voice system keeps all employees on a unified dialing plan.


The PBXgateway I easily scales with the growth of the enterprise: when new employees are added, simply utilize an available port or, when capacity is reached, add another PBXgateway.

Ease of Maintenance

Moves, adds, and changes at branch locations can be performed from a central location, as can system performance monitoring. Network and feature permissions are controlled at the central location as if all employees were under one roof. The PBXgateway I can even be remotely managed through a variety of remote access options.
