Sonim Introduces OTTO Remote Speaker Microphone with Noise Cancellation for PTT-over-Cellular Solution

AUSTIN, Texas, Aug. 25, 2020 /PRNewswire/ -- Sonim Technologies™ (Nasdaq: SONM) launched the OTTO REVO NC2 Remote Speaker Microphone, compatible with the Sonim XP8 and XP5s rugged devices. OTTO REVO NC2 Remote Speaker Microphone (RSM) features an innovative patent-pending design that provides revolutionary noise cancellation and optimum voice reception. The top-mounted microphone allows users to grip and engage the RSM without compromising audio transmission.   

The OTTO REVO NC2 RSM, when combined with Sonim devices and ESChat PTT service, provides a rugged, reliable, cellular-based PTT solution, designed for first responders and industrial workers who have to deal with extreme environments on a daily basis.  

"We are thrilled to offer the first OTTO RSM fully powered by a mobile phone," said John Graff, CMO, Sonim Technologies. "OTTO is known for their high-quality audio products for land mobile radios, and we are excited to offer the OTTO RSM for our ultra-rugged cellular devices to customers that rely on critical communications for their operations."

Key features of the RSM compatibility with Sonim's XP8 and XP5s devices include:

• The OTTO RSM is physically secured to and powered by the XP8/XP5s through Sonim's SecureAudio interface, a capability unique to Sonim devices.
• Full duplex audio supports both PTT and traditional voice calls.

The OTTO REVO NC2 RSM meets Sonim's ultra-rugged, IP-68 and Mil-Std-810G performance standards, with noise cancellation. Plus, the RSM includes a built-in debris screen to protect internal components from dust and dirt impacting transmission clarity. It includes a large PTT button, volume control slider, listen-only headset jack and emergency button. The optional listen-only earpiece jack allows for covert listening in secure, quiet settings. In addition, a built-in emergency button on the RSM is mapped to the emergency button on the Sonim device making it easy to initiate lone worker or man-down alerts. OTTO provides a 3-year limited liability warranty. The solution is available via Sonim and leading resellers in the U.S. and Canada.
