Google has announced plans to acquire Global IP Solutions, a Norwegian internet telephony company, for $68.2m (£47.6m).
Global IP Solutions makes the underlying processing software for voice and video calls over internet networks that will help boost Google Voice and other IP telephony based services.
The deal will enable Google to step up competition with traditional telecoms companies and IP telephony firm Skype, according to the Financial Times.
The deal will also mean that Google will own some of the technology that supports Cisco's WebEx system, IBM's Lotus Sametime, and the instant messaging systems.
The planned acquisition of Global IP Solutions is the latest in a string of strategic acquisitions for Google aimed at boosting its competitiveness.
In November, Google announced plans to acquire mobile advertising network AdMob in a $750m (£523.8m) stock deal to boost its position in the fast-growing industry.
The deal, which is still under review by the US Federal Trade Commission (FTC), will enable Google to combine its own search ads with AdMob's network for delivering display ads on mobile web pages and applications.
The FTC is considering whether to challenge Google over its planned acquisition of AdMob because of competition concerns.
