Cisco to Acquire SignalWorks for IP Telephony Software

Cisco Systems will acquire SignalWorks, a start-up developing high-performance audio capabilities for IP telephony systems, for $13.5 million in Cisco common stock. SignalWorks’ Acoustic Echo Canceller (AEC) software is a digital full duplex, voice-processing algorithm that improves voice clarity. The audio feature set includes multiple microphone capabilities, stereo sound, and PC-based softphones. Cisco said the technology would drive continued product innovation and differentiation across its line of IP phones and IP softphones. The software is already in use on Cisco IP telephony systems deployed by several Fortune-500 companies. SignalWorks was founded in 1994 and is based in Mountain View, California.
