The solution is in the delivery process starting from September 2016.
This project puts into practice the operator's objective of continuing the technological renovation of the internal telephone system started in 2013, in line with what it now offers its clients confirming the choice of Italtel as technological partner.
The efficiency of the solution covers all national branches. There are 3,500 users over two CUCM clusters with a Small Medium Enterprise (SME) configuration.
Each CUCM cluster is installed on a Cisco Unified Computing System B-series virtual platform and is distributed over the data centers in Rome and Milan in a Disaster Recovery configuration using the “Cluster over WAN” feature available on the CUCM.
The connection to PSTN for off-net calls is made directly on IP via the SIP protocol using the operator’s network solution already implemented for PBX IP corporate networks: this is an architecture with fixed media with Session Director proof under the control of an Italtel node.
