Critical Connect

Broadband PTT and LMR Interoperability

Interoperability between land mobile radio (LMR) systems, broadband PTT, and applications to eliminate barriers and unify communications for all responders.

LMR interoperability made easy

One link to Critical Connect connects your ASTRO 25 system with other LMR networks, broadband PTT services, and control room applications. And, Critical Connect separates itself from traditional solutions by enhancing interoperable communication with features such as private calling, automatic roaming, grouping/regrouping, and end-to-end LMR encryption.


One secure connection provides seamless communication with internal groups and external organizations, reducing the cost and complexity of interoperable PTT.


Select with whom you want to connect from the other agencies and broadband PTT services linked to Critical Connect, quickly setting up and tearing down connections as needed.


Monthly subscription fee allows you to adjust level of service quickly and easily as needs grow.
