The U.S.-based communications company has extended its outsourcing relationship with a customer care, human resources and billing services provider, Convergys.

Under the expanded contract that includes a 12-month extension of Infinys license support and maintenance and an agreement for consulting services, Convergys will continue provide relationship-management solutions to the customer.

The provider will also consolidate its seven different legacy-billing systems with more than 30 million subscribers onto a single billing and order-management solution. In addition, the customer has deployed Infinys as the backbone of its new open business infrastructure.

In fact, the customer has also extended an agreement with Convergys for its consulting and services team to provide comprehensive operations support.

Last month Convergys also bagged a new, multiyear contract from Bharat Sanchar Nigam (BSNL), an Indian telecom-services provider, to providing billing solutions and to support the customer’s 18 million wireline subscribers.

After announcing its deal with BSNL, the Cincinnnati-based $2.8-billion company, which employs 75,000 employees globally, also revealed its intensions to looking at partnering telecom companies helping them in billing-solutions area.
