Seine-Saint-Denis Department Council

The Departmental Council of Seine-Saint-Denis, with nearly 7,000 employees, is a major public employer in the Île-de-France region. Its missions cover a wide range of public services: social assistance, culture, leisure, road maintenance, transport, and education.

At the time, the annual allocation for middle schools was around 800,000 euros. We brought it down to 150,000 euros. That represents a very, very significant economic gain for the Department.

The Seine-Saint-Denis Departmental Council modernize their telephony

挑战

In 2007, the Department faced an aging and highly heterogeneous telephone infrastructure. A central system managed around 3,000 employees, while the remaining 4,000 were distributed across local PBXs, one per site. This setup led to:

Significant hardware obsolescence
Complex management of technical skills
High maintenance costs
Limited flexibility to adapt to evolving needs

行动

A master plan was developed to modernize the entire telephony system. After approval by General Management and the launch of a public procurement process, the OmniPCX Enterprise solution from Alcatel-Lucent Enterprise was selected. The project was entrusted to Hexatel, a systems integrator recognized for its expertise in ToIP migration.

The deployment spanned approximately ten years, with a gradual migration plan covering several hundred sites. In 2016, the scope expanded to include 130 middle schools, bringing the total number of sites to over 400.
