Dixons said it hopes the deal, which was announced this week, will support its continued growth and cut overall costs.
As part of the contract, Energis, which already hosts Dixons' e-commerce sites, will provide direct-access telephony at Dixons headquarters. The system will carry both inbound and outbound calls on Energis lines.
The deal also includes a carrier pre-selection application which will be deployed at the retail branches of PC World, Curry's, Dixons and The Link. This is designed to enable the stores to easily route their telephony traffic over the Energis network and monitor billing and performance information online.
The Dixons contract comes hot on the heels of the multimillion-pound networking contract that Energis, which was bought out for just £150m last month, signed with supermarket chain Tesco last week.
