V²oIP Suite

Current IP Communications technology permits home and small/medium sized businesses to use their network connection in novel ways. V²oIP (Voice and Video over Internet Protocol) applications can treat voice, video, data, or facsimile as simple data, which may be packetized and transmitted in real-time over IP networks.

VOCAL's robust and comprehensive suite of V²oIP software libraries provide the foundation for our Video PBX Reference Design Kit, offering licensees a complete voice and video solution. Since we provide both the hardware design and optimized software (including our state of the art On-One™ DSP technology), VOCAL can provided unsurpassed advantages in cost and time-to-market potential.

The software includes a Network Stack, SIP Stack, full-featured Telephony software, as well as a wide range of VoIP vocoders and video codecs. Together with SRTP, SDES, IPsec, and our encryption libraries, VOCAL's VoIP software can ensure privacy and security of all communications. Also present is Quality of Service (QoS) support; efficient prioritization of existing bandwidth can ensure maximal throughput and best possible media quality.

Applications of our V²oIP Suite include:

• Videophone
• Enterprise communications with videoconferencing
• IPTV
• Streaming video and audio players
• Information appliances
• Home media gateway
