Abstract
The present invention includes methods in an interoperability system for: notifying a user in a first communication system that a trunked radio system is ready to receive data; broadcasting or distributing an emergency announcement from a trunked radio system to the other radio systems in the interoperability system; a user of one communication system using vocalic commands to establish a patch with another radio system; and enabling a PSTN device to more effectively communicate with radio systems in the interoperability system.
