ESChat today announced commercial availability of its latest server release, which includes enhanced P25 Inter-Sub System Interface (ISSI) support for P25 Phase II trunking systems.

Also included in this release is support for TIA-102 compliant Key Management Functions (KMF) encryption re-keying. ESChat had previously deployed ISSI based interoperability for P25 systems in March of 2017. Support for P25 encryption over ISSI was added later in the year, however the initial release required encryption key loading be performed via ESChat’s key-loader utility application.

“This release is significant for a number of reasons,” said Josh Lober, Chief Executive Officer, ESChat. “On the KMF side, we have a number of existing deployments with contractual obligations to support OTAR re-keying, including the Dallas Fort Worth (DFW) Airport. As for P25 Phase II support, we have a number of orders pending which we are now able to fulfill”.

Support for P25 Phase II over ISSI and KMF re-keying are the latest elements to a larger set of system enhancements. Other ESChat features recently added include; Client-Side Playback, Emergency Group Calls, Listen Only Group Members, Configurable Idle Timeout and Hierarchical Departments.

ESChat will be demonstrating these and other advanced Broadband Push-to-Talk features at the International Wireless Communication Expo (IWCE) in Las Vegas, NV, which takes place March 4th – 8th.
