The CLASSONE iExtreme® SIP-Based Radio-Telephone mobile PTT application takes priority handling, rapid personnel deployment and dispatch management to the next level. Mobilizing communications channels is vital to the survival and growth of every organization. Unlike legacy radio dispatch console technologies, the iExtreme enables dispatchers, field operators, managers and executives an immediate and unassisted access to every radio and telephone channel in real-time for faster response and decision-making. This application along with our SIP-Based Console applications can be deployed to a cloud architecture managed by INEMSOFT’s ClassOne® Endpoint Manager®. The Endpoint Manager provides mobile devices with provisioning data, firmware, setting files, and ctivation. This architecture allows secure, remote and instant communications with field operators and dispatch personnel. The iExtreme Mobile PTT application supports call center ACD Agent functions allowing an organization to optimize and manage its workforce using call center best practices and tools. Managers are now capable of monitoring workflow, call distribution, call volume, tracking of call statistics and identifying peak call times and events to steer occupancy level within the network and field operations.

The call waiting screen allows the user to be fully aware of all concurrent inbound phone and radio calls so that you address calls based on critical information. Includes one-touch tools such as call arrival times, priority, number of call attempts, caller id, call state swipe to transfer, answering and dropping calls, and automated priority background color to differentiate between call types.


The ‘Operate Stack’ and ‘Monitor Stack’ allow users to manage their active telephones and radio calls with a one-touch swipe right to Operate and swipe left to Monitor feature. The active stack uses a color indicator for visual identification, as well as a full telephony suite of tools such as Mute, Hold, Conference, Transfer and End Call, audio volume control sliders on both stacks, and the ability to operate to talk while monitoring other calls at the same time


Users can configure the most frequently used destinations to be on the speed dial list by simply tagging the preferred contact. Speed dial icons can be rearranged as needed, and users can trigger a call by simply tapping on the icon. Speed dial cells have indicators to visually represent any audio activity. In addition, a presence indicator will display real time information to show the status of the speed dial contact.


iExtreme® comes with its own keypad interface with an autocomplete suggestion service based on the corporate directory, independent of the mobile device records. As-you-type suggestion shortcuts are displayed to speed up and enhance the user experience. DTMF is supported with tone operated devices such as radio base stations, voicemail and priority services.


The More button contains many additional features and tools such as user online status (aka Call Center ACD Ready, Work Not Ready, and Not Ready), network connectivity status to ClassOne® server, SVR and SIP session registration, inbound and outbound dynamic history records, priority broadcast, and the iExtreme App Settings including Endpoint Manager configuration, and much more.


Corporate directory records can be imported directly into your profile upon login or you can create your own. Either way all records are synchronized with the ClassOne® database to ensure availability as well as stored locally on the device to ensure business continuity during outages. Users can receive tailored phone, radio and group records to their devices.


Includes an archive of all inbound and outbound calls within the iExtreme® application. Call history records are stored locally on the mobile device and synchronized with the ClassOne® database server for future reference. History records encapsulate full contact and call details such as timestamp, date and call duration for user validation.


Provides a secure link to the cloud-based Endpoint Manger® server for user access authentication and mobile endpoint activation. Users can switch features on and off, for example enabling Monitor Conference feature to monitor many radios at the same time, configuring the application to run over VPN or LTE/WIFI, setting up SIP account configurations, and much more.
