Rolls-Royce is spending $20m to move to a single voice network running VoIP, in a seven-year deal.
Under the managed services agreement, Nortel will become the preferred provider of enterprise telephony for the engine giant's new global voice network, which will serve 26,500 users in Canada, France, Germany, Norway, the UK and the US.
The new voice network will provide voice, fax and email services, and see the introduction of new mobility services.
Nortel will provide services including design, integration and deployment of IP telephony equipment and software, along with management and maintenance of the existing TDM-based network and the new VoIP network.
Rolls-Royce IT purchasing director Jim Reed said one reason Nortel was chosen was because it understood how to simplify Rolls-Royce's network infrastructure.
Nortel's network management and maintenance will include remote fault monitoring and network surveillance; SLAs for response and resolution; moves and changes; and reporting. It will use Nortel products including Nortel CallPilot and Nortel Communication Server 1000.
