Under the terms of the deal, C&W will provide a full communications suite including 72 separate services, including voice telephony, data, local and wide area networks and international services — to Aviva’s 35,000 staff based in the U.K. and India.

As part of the deal, which extends to 2014, C&W will continue to manage Aviva’s existing communications infrastructure as well as introducing services, including IP contact-center services across Aviva sites in the U.K. In total, the network will comprise more than 1,000 sites, with 57,000 individual telephone points and 74,000 data points.

In addition, Aviva will also utilize C&W’s infrastructure and experience in India under the contract.
