US : Sonim Technologies, the leader in enabling today's wireless data networks to deliver high-margin VoIP applications, today announced it has successfully completed the industry's first Open Mobile Alliance (OMA) compliant Push to Talk over Cellular (PoC) call over the UMTS network.

This announcement underscores the company's commitment and deep involvement to developing and applying new standards with OMA PoC and PAG, and showcases a milestone achievement with its recently announced OMA-compliant Sonim Xperience(TM) PoC Client (XPC). Existing and prospective partners that seek to add market-proven functionality into handsets will now have the opportunity to lead the pack with early-to-market UMTS PoC handsets.

"Sonim is delighted to be the first to provide an OMA PoC solution for the UMTS market," said Joakim Wiklund, Chief Technology Officer for Sonim Technologies. "The Sonim PoC Clients have already enabled the handset manufacturers to deliver a portfolio of cutting-edge PoC compliant handsets for the market. As more than a hundred of mobile operators worldwide have deployed UMTS networks, the Sonim XPC fulfills demands from these operators for the next generation of standards-based clientware."

"Sonim's early and innovative work with Push To Talk over Cellular influenced the standards and developed strong competence delivering VoIP applications in demanding wireless markets," said Ken Rehbehn, Research Director for Telecommunications Infrastructure at Current Analysis. "Building on this experience to deliver solutions for UMTS means that operators can continue to expand the service repertoire - and do so with confidence."
