The eyeBeam SDK is comprised of more than 30 low-level APIs including the following: Audio Mixer, Video Mixer, HTTP, STUN, SIP Stack, SIP Call Control, SDP, RTP, ICE, DNS.

"Yak's first principle is to deliver extraordinary value to our customers, whose primary calling patterns are long distance calls in North America and worldwide," said Charles Zwebner, Chairman and Chief Executive Officer of Yak Communications. "The partnership with Xten Networks is expected to provide our customers with benefits that historically have been cost prohibitive to them. Now our high speed VoIP customers, in addition to being able to make inexpensive calls to anywhere in the world, will also be able to video-talk, free of charge to any Yak VoIP customer globally. We see the use of VoIP technology as the beginning of a global movement in 2005, where consumers and small businesses will want to take advantage of a truly plug and play high tech environment. Using our VoIP products and services, Yak customers not only will receive more calling time, but also video calling time at a low price point. Yak is on target to begin aggressively marketing our VoIP products and services, and we are excited to commence this program in the next few weeks," added Zwebner.
