VoIP services modernized for Poste Italiane
SOLUTION
TIM and Italtel have jointly designed and deployed – within a Raggruppamento Temporaneo di Imprese (temporary group of companies) in which TIM is lead – the evolution of the Voice-over-IP (VoIP) infrastructure of Poste Italiane.
Poste Italiane is the Italian largest company operating in postal delivery, logistics, financial and insurance services, and digital communication, with network capabilities across the country. Poste Italiane's VoIP renewal project was launched with the goal of providing new and improved services to the company's internal users, including about 13,000 post offices across Italy, while reducing infrastructure costs. Overall, the private network of Poste Italiane serves more than 50,000 users, who use various types of devices thanks to TIM’s broadband and ultra broadband connections.
For the modernization of Poste Italiane's network, Italtel has designed a solution based on state-of-the-art technology. More specifically, this a fully virtualized solution, following the Network Function Virtualization (NFV) model, which extends the logic of Cloud Computing - typical of IT contexts - to the telecommunications sector.

The solution adopted by Poste Italiane:
1
benefits from the availability of HW COTS and the best software components on the market (Hypervisor, Carrier Grade Operating Systems, Commercial Database, etc.)
2
adopts the most innovative standards (3GPP, TISPAN, Oasis, IETF, ITUT)
3
replaces some existing network elements with new products
The new infrastructure comprises several Italtel products: the Core and Border IMS/NGN i-MCS suite, the sunscriber data management solution i-TDS, the management element i-NEM, the Session Border Controller NetMatch-S, both as User-Network Interconnection (UNI) and as Network-Network Interconnection (NNI).
BENEFITS
The modernization solution has been specifically designed to enable Poste Italiane to evolve its current platform in an absolutely continuous manner and with minimal impact on its services.
All this thanks to the full compatibility between new and existing products and by leveraging over proven migration operations that provided a smooth transition to the final architecture, with minimal impact on the network configuration and active services, even in terms of user experience.

The most important success was the migration of about 700 GNR H323s (which can provide for several thousand users) and over 20,000 SIP users in a very short time. The project was completed in approximately 2 months, within the deadline requested by the customer.
Moreover, the new solution enables considerable cost reduction by optimizing the centralized infrastructure area within the TIM Data Center by 75%, and by reducing the energy consumption resulting from the activation of one of the largest VoIP platforms in private cloud logic.
Two devices occupying half of the rack are now sufficient to provide the functionalities which in previous solutions required several racks.

All validation, migration and troubleshooting activities were carried out remotely by Italtel test plants in Castelletto di Settimo Milanese (Milan).
