Voice over Internet Protocol (VoIP)

Today's telephony network infrastructure is changing in leaps and bounds. One of the biggest changes is that telephone landlines are being replaced by ADSL and cable. Voice over Internet Protocol (VoIP) has entered our business while many houses now have Ethernet connections, from which telephones can be connected wirelessly. Consumers are turning more and more to features that Ethernet offers for cheaper connectivity to friends and relatives around the world.

Currently, fixed-line telecom providers are competing with Internet Service Providers (ISPs) to bring in a new revolution by cashing in on the communications market using their own standards. Fixed-line telephone providers have focused on stand-alone base stations using Session Initiation Protocol (SIP), while internet service providers focus on Voice over Instant Messaging (VoIM) protocols.

Session Initiation Protocol (SIP)
We take care of every aspect of the hardware platform for VoIP cordless applications. Our ICs, used in SIP base station applications, offer direct connections to your modem allowing you to make VoIP calls using the SIP while offering backwards compatibility between VoIP handsets and Generic Access Profile (GAP) handsets. Also, we have developed modules to be used in SIP boxes and offering direct connection to your standard analog telephone line too. This application allows you to use your phone for cordless analog line connection or as a cordless VoIP link for maximum flexibility.

Voice over Internet Messaging (VoIM)
VoIM provides a method of making cheap or even free telephone calls to fellow subscribers via the Internet using e.g. Google, MSN or Skype. Apart from the obvious cost reductions to the consumer, this revolution opens a whole new world of features. Embedding the DECT cordless standard into the computer environment allows users to apply and enjoy these features.

Working closely with handset, router and cable modem manufacturers, we have designed components for handsets and base stations (routers) that connect to:

  • PCs using a USB interface to run VoIM: The PC runs software protocols as set by the Internet service providers
  • Ethernet using embedded VoIM protocol: The Internet service providers' software protocols are now running over a standalone base station
  • Ethernet using embedded SIP protocol in order to run VoIP
Our components can be adapted to any of these protocols. Thanks to the flexibility of our base band architecture, telephone manufacturers can now answer today's consumer needs easily, simply by modifying the software protocols.

Our products cover the whole market for SIP, VoIM and VoIP applications. And because we see tomorrow's living environments depending more and more on Ethernet hubs, we are developing technologies that will be compatible with Ethernet and WiFi connectivity in the home.
