AT&T Enhanced Push-to-Talk can be utilized not only as a overlay broadband data network but also as a redundant network in the event of a LMR network outage.
Supports PTT integration with mobile applications
Utilizing a suite of APIs, AT&T Enhanced Push-to-Talk service can integrate directly into mobile public service apps and consoles.
Delivers fast cycle time to operational service
