## What is MCPTT?

MCPTT is mission critical push-to-talk built by a 911 center, for the people who answer the call. Press the button and every unit on the channel hears you, on LTE, 5G or Wi-Fi, over FirstNet, T-Priority, Verizon Frontline or any other carrier.

Anyone can use MCPTT. It is built for police, fire, EMS, 911 centers, utilities, hospitals, schools and the private security and critical infrastructure teams that work alongside them.

BUILT BY PUBLIC SAFETY
MCPTT is designed, built and maintained in the United States, in joint operation with the Coosada 911 Communications District in Alabama and Echo911. The people who run it dispatch on it every day. Two sites carry voice at all times; if one is unreachable your radio moves to the other without you noticing.

STANDARDS, NOT LOCK-IN
MCPTT follows the 3GPP Mission Critical (MCX) specifications for MCPTT, MCData and MCVideo. Unlike carrier-bundled or radio-manufacturer PTT, it is not tied to one network or one hardware brand. Use the phones and radios you already own, on the carrier your agency chooses, and move between them without losing your talkgroups or recordings.

CONNECT TO EVERYTHING YOU ALREADY HAVE
MCPTT ships with an open API and LMR interconnection built in, not sold as an add-on:
- P25 ISSI and CSSI
- DMR AIS
- SIP trunks and SIP endpoints
- CSoft, Telex and other RoIP platforms
- 3GPP MCX interworking with other MCPTT providers
- REST API for CAD, RMS, dispatch consoles and your own tools

TALK
- Channels for your agency, your region and mutual aid
- Scan up to eight channels with one priority channel that always breaks through
- Private calls and call alerts to any unit
- Works with Bluetooth remote speaker microphones, including the Motorola WM500, and wired PTT accessories

SEE
- Live map of your units and your own devices
- Location shared automatically during an emergency

HEAR IT AGAIN
- Every transmission is recorded and kept on the server, not just on your phone
- Missed calls are flagged; play them back one at a time or play everything newer in order

STAY SAFE
- Emergency button with open mic, location and dispatcher acknowledgement
- Encrypted between your device and the service, with hardware-backed device keys and per-device enrollment approved by your agency

Sign in with your agency email or scan the QR code your administrator gives you. An agency account is required for talkgroups, recordings and the map. Private calls may be monitored by your agency.
