Dallas International School (DIS) is a pre-K through grade 12 private school with a bilingual academic program. DIS is a member of the Mission Laïque Française, a global organization that promotes French language education.

  • Country: United States Of America
  • Industry: Education
  • Solution: Business Telephony

DIS has 700 students and about 150 faculty members across 2 campuses: Churchill (pre-K through grade 4) and Waterview (grades 5 through 12).

DIS wanted a solution from a company with name brand recognition like Alcatel-Lucent Enterprise. 
Availability of local support was also important. ICON Voice Networks, the Alcatel-Lucent Enterprise master distributor, and Advance Integrated Networks, the local integrator, both have a presence in the area that enables DIS to quickly receive equipment and support.

Reliability of communications is critical in a school environment and our existing infrastructure was failing us. The Alcatel-Lucent Enterprise solution gives us the dependability and scalability we need, while delivering great features like voicemail to email and PIMphony call management.

Douglas Lee, Director of Technology, Dallas International School


  • The telephony system in Waterview was no longer meeting DIS’ needs.
  • Chronic issues, including handsets going offline without warning, resulted in unreliable service.
  • Time-consuming manual reboots were required every month to keep the system operational.
  • In addition, DIS wanted to increase safety by enabling students and staff to make emergency 911 calls without having to first dial 9 to get an external line. 
  • The school required a scalable solution to support the planned growth of the Waterview campus.
