Cisco plans to acquire two privately held firms to flesh out its convergence and wireless product range in stock-swap deals valued at $501m (£318m).
The networking company will buy wireless telephony specialist JetCell for $200m, and internet appliances and software developer InfoGear for $301m.
JetCell develops wireless technology to enable companies to make voice-over-IP calls using standard GSM networks. A Cisco spokesman said the offering was currently in trials and large scale deployment is expected in the next nine months.
The technology will be integrated into Cisco's Avvid initiatives to enable traditional telephone networks to work in IP environments.
InfoGear's software lets customers remotely manage and upgrade information appliances from a central location and deliver customised content to a host of web devices. The technology will form part of Cisco's so-called New World strategy covering the convergence of data, voice and video services.
