(OTC Bulletin Board: TNXI), a leading communications solutions provider offering next generation voice services and video telepresence solutions to the business market, today announced the expansion of its contract with CallSource, a provider of call tracking technologies that enable companies to increase their marketing effectiveness, capture additional sales opportunities, and improve customer service. Telanetix will be providing CallSource with many of its business phone services, including Local DID, Toll Free, and US and international Long Distance, all based on Telanetix' nationwide VoIP Network.

"The expansion of our relationship with CallSource is an example of the success we are having in our continued growth and investment in delivering voice services to the Small and Medium Business marketplace," said Doug Johnson, CEO of Telanetix. "CallSource is an important customer and the best vote of confidence comes from a customer who has a long history with you and chooses not only to continue that relationship, but to add to it. We believe this is a positive sign for both of our companies and also for those who continue to serve the greater SMB market as a whole."

Founded in 1994, CallSource is a leading provider to the automotive, multifamily housing, publishing, and advertising markets, plus thousands of other businesses across a number of industries. CallSource manages more than six million phone leads each month for over 250,000 advertisers.

"We are increasing our use of Telanetix services because we have found that the company provides an excellent value and performs at a very high level," Elliot Leiboff, Chief Strategy Officer of CallSource, said. "Our business depends on delivering dependable phone service to our business customers. Our business model depends on delivering that service at a great value.
