Telefonica Chooses Sonim's XP1 ''Tough Phone''

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 Moviles
Espana 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 Moviles Espana has chosen our handset for its customers."
