San Diego, CA and Burnaby, BC, Canada — December 11, 2003 —

SIPPhone, Inc., (www.sipphone.com) and Xten Networks (www.xten.com) today announced that they have joined forces to bring free telephone calls and conferencing to the masses. Xten softphones turn computers into business class telephones and offer unlimited user conferencing at the click of a mouse button. SIPphone delivers a feature-rich and free telephony network, and hassle-free configuration.

Free phone calls and conferencing are the key to delivering true global communication to the general public.

"This partnership eliminates the barriers to entry between consumers and free worldwide calling," stated Michael Robertson, Founder of SIPphone Inc. "By turning the common PC into a global calling tool and providing customers with free conferencing -- an industry first -- telecommunications have finally been democratized."

"The ability to communicate with anyone, anywhere, should be the right of everyone, not just those who can afford it," stated Erik Lagerway, co-founder and president of Xten Networks Inc. "This new alliance will empower all the world with free voice communications, a novel concept for the incumbents who have made trillions from offering the same services. The next 3 years will dictate how the future of the telephony industry is shaped, due in great part to services like SIPphone."

SIPphone makes it possible for people to send and receive free calls worldwide using a technology called SIP, for Session Initiation Protocol. To make a SIP call, a supported SIP phone is plugged into a broadband Internet connection, the desired SIP number is dialed, and the call will be connected. All SIP phones come preconfigured with a SIP number (for example: 1-747-474-5000). This number can be shared with anyone with a SIPphone. SIPphones also support caller ID and call-waiting, all at no charge.

Conferencing is becoming more commonplace, and Xten softphones offer unlimited conferencing at the click of a button.
