Radianz, the financial services extranet provider, has completed its disposal of non-core assets with the sale of its voice trading operations to WestCom Corporation, a US-based telecommunications company. The sale comes as Reuters, the information firm which owns 51% of the business, tries to strengthen Radianz in preparation for the sale of part or all of its stake.

The extranet has sold Radianz Voice Services in an undisclosed cash transaction. The deal was completed last Thursday when WestCom received all of Radianz' voice services customer contracts, as well as its total European and most of its US staff.
