VoIP technology

Dialog Semiconductor is delivering high quality, ultra efficient VoIP applications. Our Green VoIP processors combine industry-leading power consumption with the flexibility and processing capacity to handle a wealth of enterprise VoIP applications.

Combining a wide range of narrowband and wideband VoIP codecs with state-of-the-art acoustic echo cancelling, the ICs deliver a crisp and natural voice in all environments.

The technology’s flexibility enables the creation of a wide portfolio of devices whilst using the same processor family; from a basic desktop phone to advanced systems with a suite of software applications and support for wireless and Gigabit Ethernet connections.

Dialog works closely with industry bodies to define and implement new open standards and technologies. For VoIP technology, our solutions focus on the session initiation protocol (SIP) for maximum interoperability with IP-PBX vendors.
