Sonim Technologies, the leader in push-to-talk IMS solutions for operators and the global provider of high-performance mobile VoIP applications and devices, today announced that Telefonica Móviles España has chosen the XP1, a durable, ruggedized handset that offers push-to-talk functions in extreme environments. Sonim designed the XP1 to comply with the Open Mobile Alliance Push-To-Talk-Over-Cellular (OMA PoC) standard, offering instantaneous one-to-one or one-to-many communications capabilities. The XP1 will work with the Nokia OMA PoC-compliant server to provide a complete, certified push-to-talk solution for Telefonica.
Sonim’s XP1 is designed to operate in outdoor and environmentally harsh conditions, and the handset is IP52-Certified, making it resistant to the two most prohibitive conditions for outdoor use: dust and dirt. The XP1’s durable features, combined with its OMA PoC certification, make it an ideal communications device for industrial and municipal workforces.
“We designed the XP1 to target users needing a durable handset that functions in extreme environments,” said Albert Costilo, senior director of southern Europe at Sonim. ”We are excited and proud that Telefonica Móviles España has chosen our handset for its customers.”
