IP Server 900

IP Server 900 business telephone system

The IP Server 900 is a high-performance IP phone system that unites the communication and productivity needs of end users in small-to-medium organizations with one or more sites. The system's expandable design integrates built-in capabilities, advanced features, and highly differentiated applications into a product that's as easily used and managed as it is flexible.

The IP phone system your business needs

Telco Ltd. will customize your IP Server 900 to fit the needs of your business, whether you have a small office or hundreds of employees, building on this powerful foundation:

Powerful — but friendly

Despite its long list of features, an IP Server 900 — thanks to famous ESI ease-of-use — is a truly user-friendly phone system. It says, “Good morning.” It teaches you how to use and program it. It reminds you to change your personal greeting after a trip. And it stands by, ready to assist you whenever you need help. There are several different models of ESI desktop phones. Each is a compact, attractive addition to any desk, designed to simplify your telecommunications. Here are just two examples:

  • The display is large and easy to read; that's even more true for a backlit display, which comes standard on most models.
  • The dedicated function keys (so you don’t have to memorize codes) give you more ease of use, even with an IP Server 900’s enhanced capabilities.

Easy to choose; easy to use

The IP Server 900 is an easy choice over other business communications systems. Its ease of use and feature-richness reduce staff frustrations, increases productivity, and enhances your corporate image. And its unique integration provides call-processing efficiency and cost savings that previously were impossible.

The Details:

  • Overview

    The capacities described below are maximums, which will vary based on your IP Server 900’s configuration and licensing, as well as the extension dialing plan (four-digit or three-digit).

    • Better business communications through IP
      The IP Server 900 is an appliance that combines the reliability of a traditional phone system with the flexibility of network connections, using Internet Protocol (IP) technology. This improves your business communications — delivering enhanced customer satisfaction, increased productivity, and an improved bottom line.
    • Scalability
      The IP Server 900 is built to grow with your business — intelligently. And, thanks to the large number of features the IP Server 900 shares with many other ESI systems, past and present, retraining is minimized if you migrate from one model to the next. You can start small and grow as large as you’re likely to need — up to 192 outside lines and up to 864 stations. Additionally, if you have access to high-bandwidth service, there’s support for up to 192 T1 channels or 168 PRI lines.
    • Powerful voice mail capabilities
