VoIP System in USA

El Dorado Public Schools

“With the Xorcom solution, it is easy to move a teacher to a different classroom by just picking up the phone and moving it – much easier than with the traditional phones!” “4-digit dialing between the different schools greatly reduced our expenses.”

“With Xorcom, we didn’t have to change our network switches, we were able to fully implement the proper VoIP design on the existing infrastructure. That’s a big deal, when you talk to the other major vendors they want to replace the switches, since they will only work with a specific vendor. This is a key factor, especially when comparing costs.”

“Choosing Xorcom enabled us to invest more money in the hands of the kids, in the form of laptops and i-Pads, rather than replacing network equipment.”

Joe Taverner of Tavtech notes: “One of the main reasons for choosing Xorcom: there is no per user or per device licensing fee, and no fork-lift upgrade necessary on the existing network infrastructure to implement the solution.”

VoIP System Installation in USA – Overview

The El Dorado Public Schools in Kansas are comprised of one high school, one alternative high school, one middle school, and four elementary schools. The high school and middle school is “1:1” (one wireless device for each student – laptops for high school, i-Pads for middle school). Grades 4 and 5 are moving to a 1:1 with iPads in January of 2015. To support this high tech approach, Doug Jensen, Director of Technology for the school system, was looking for an affordable IP solution that would be easy to deploy in the classrooms and throughout the administrative buildings. The current equipment included decades-old Toshiba (and a somewhat newer NEC) analog systems. Over time they added MultiTech gateways in order to be able to put IP phones in every classroom, and link El Dorado Public Schools – Xorcom Case Study Page 2 of 4 Xorcom USA 145 South Jefferson Ave., Suite G Cookeville, TN 38501 USA Tel: 866-XORCOM1 / 866-967-2661 [email protected] www.xorcom.com Xorcom Ltd.

Although this was a relatively inexpensive way to get everything connected, at the end of the day it was two different systems – a maintenance hassle. So, about four years ago Doug started looking for an alternative. He quickly eliminated the proprietary systems, which were quite cost-prohibitive, and started researching Linuxbased phone systems. Joe Taverner at TavTech introduced him to Xorcom.

In addition, schools that serve higher poverty populations get more support for equipment. In the past they could fund phone systems through the e-Rate program. They’ll now need a less expensive phone system to cut costs, as it will be hard for them to justify continuing with high cost proprietary systems. Xorcom systems, with their ability to utilize existing infrastructure while providing the benefits of VoIP with no per user license fees, provides the right combination of advanced technology and cost-effectiveness.

Customer Voice Communications Requirements

  • Place an IP phone in each classroom
  • Interface to traditional intercom system via 2-digit and 4-digit dialing (from anywhere in the building – announcement or emergency)
  • Allow teachers to immediately contact the office, and each other
  • Support voicemail to e-Mail
  • Follow-me from desk phones to cell phones
  • Enable 4-digit dialing between all schools

Proposed VoIP Solution

Tavtech suggested installing the Xorcom XR3000 at the central office, and CXE2000 / XR2000 at the larger elementary schools (the smaller elementary schools have an XR1000 and Astribank, respectively), along with Yealink IP phones (T28 for administrators, T22 for classroom devices). A dedicated VoIP VLAN is used in the network to separate out the voice and data for Quality of Service (QoS) purposes. This is especially important between sites where one might have lower bandwidth connection. The existing Dell switched infrastructure was utilized to accomplish this. This is a key factor, especially when comparing overall costs. Replacing the entire system, including switches, could result in a per extension cost of between $500-$1000, as compared with $250 per extension using the existing infrastructure. The Xorcom solution is also in line with the recent proposed updates to e-Rate, the federal government funding program for schools. Up until the summer of 2014, schools could get reimbursement from the federal government for phone expenses. The government has decided to wind down support for analog lines and digital phone lines.


The first Xorcom system was installed about three years ago in the central office. Every time a new school was built the Xorcom installation was extended. The older schools have gradually been updated to replace the Toshiba PBXs with Xorcom. The only outstanding school system is the high school, which is scheduled for replacement this summer. A standard configuration, including provisioning templates for the Yealink IP phones, makes installations a breeze. Doug oversaw implementation of three Xorcom systems last summer for three different elementary schools. It took basically one day for each, with 20-40 extensions per building, although the middle school is somewhat larger than that. All the schools are connected with 4-digit dialing. This greatly reduces expenses by enabling consolidation of the lines at corporate, and then utilizing the data lines which already exist as dark fiber (unused fiber-optic cable) between all schools in the system.
