The iNEMSOFT ClassOne® IP Radio Gateway enables full interoperability between various radio types and the telephone network over IP/SIP trunks. It supports mobile radio access, radio-to-radio bridging, inbound and outbound dialing, and connectivity to any back-office telephone system. Previously incompatible radio types, channels and frequencies can communicate seamlessly with each other and with telephones, mobile and smart devices.


The iNEMSOFT ClassOne® IP Radio Gateway provides command and control for various types of radio traffic over the IP/SIP protocol, including UHF/VHF, narrow band, 700/800 MHZ digital and P25. It supports various methods and protocols for activating and accessing radios, including “push-to-talk” by authorized off-network voice devices.


The iNEMSOFT ClassOne® IP Radio Gateway is designed to operate concurrently with existing legacy and radio dispatch systems during a migration to a new IP-based platform. As a result, day-to-day operations will not be interrupted during the move to new technology. You are able to make a gradual transition and can choose the right time to step away from your legacy system. iNEMSOFT provides operational stability and risk mitigation during the migration process, whether the transition happens over days, months or years.


The iNEMSOFT ClassOne® IP Radio Gateway leverages the latest-generation standards for VOIP over SIP/IP and Internet routing. This IP/SIP foundation enables full device interoperability with radios, telephones, mobile and smart devices. It also enables remote installation, provisioning and maintenance.
