Cisco Systems is enhancing its unified communications offering by splashing out $48m (£28m) to acquire two technology start-up companies.
The technology acquired will allow Cisco to offer customers new and easier ways to merge their business software applications with their IP-based communications systems.
Cisco is paying $28m for Metreos, which has 19 employees, and $20m for Audium, which has 26 staff. Both are based in the US.
The technology bought will be used to build and deliver applications using Cisco's Unified Communications System. This is a suite of voice, data and video products and applications, which are designed to help integrate firms’ communications with their IT infrastructure.
The solutions from Metreos and Audium are effectively middleware, which enables developers and integrators to more easily link communications and IT together.
The Metreos and Audium products will be integrated into Cisco's Voice Technology Group. Cisco had already been working with the companies as technology partners.
