ESChat Interoperability Network

Interoperability has emerged as the greatest challenge in broadband PTT communications, and ESChat does Interoperability better than anyone.  The two key areas of interoperability are Inter-Carrier Interoperability and Inter-System Interoperability.

You’d think that providing secure PTT communication across wireless carriers would be fundamental to all PTT services, but it’s not.  ESChat provides cross-carrier interoperability without the need for gateways, special applications or incremental fees.

Inter-System Interoperability is the ability to seamlessly communicate between ESChat and other communication platforms, including Land Mobile Radio (LMR) networks, Dispatch Console systems and Logging Recorder Systems.  ESChat can interface with any LMR network, regardless of frequency band or modulation technology. ESChat provides both basic Gateway based interface solutions for Inter-System Interoperability, and also advanced Wireline interfaces solutions.  Wireline solutions communicate without gateways, using standards based protocols that include: ISSI for P25 trunking networks, AIS for DMR and Dispatch networks, and SIPREC for logging recording networks.  Numerous companies have also integrated ESChat’s SDK’s into their Dispatch and LMR gateway solutions for an improved set of advanced interoperability features.
