EXTender™ 4000

Extend the features and functionality of a central PBX to home-based workers with IP lines.

Key Features

Citel’s EXTender 4000 gives workers in Small Office/Home Office (SOHO) environments seamless remote access to the corporate voice and data networks, and associated applications, utilizing DSL or a cable modem.

To install the EXTender 4000 solution, simply connect a unit to a compatible digital deskset and a broadband Internet connection at the remote location, and a compatible PBXgateway at the PBX location. Set-up is easily accomplished using the phone display or a PC. With the optional second Ethernet port, a PC may also be connected to theEXTender.sm_EXTender_4000

Key Benefits

Increased Productivity

SOHO workers use the same full-featured digital PBX handsets as the central location to access PBX/KTS dial tone, receive office-bound calls, and invoke business calling features such as internal dialing, transfer, hold, and conference. Users who also maintain a workstation at the corporate office can provide callers with a single reach number, and enjoy the convenience of one voice mailbox for all messages. Straightforward configuration and management allows IT and telecom staff to focus onemployee productivity instead of remote voice system maintenance.

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 (fourdigit) dialing, there are no toll charges when calling any extension 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 EXTender 4000 interoperates with all leading PBX/KTS systems, allowing remote users to connect to the corporate voice system via the existing PBX or KTS. New teleworkers and other single remote users can be easily added with an EXTender 4000 deployment at the remote location, and a PBXgateway port at the PBX.
