Abstract
A system and method for sending notifications of audio tone sequences to users in a push-to-talk over cellular communication system, including: decoding an audio transmission in a PTT (push to talk) server or in a PTT client, identifying audio tone sequences in the audio transmission, and sending from the PTT server or from the PTT client notifications of the identified specific audio tone sequences to users of cellular mobile devices, computers, and two-way radio communication devices. The notification may be a text message to a predefined PTT group, a delayed buffered replay of the audio transmission, the specific audio tone sequences with the audio transmission before and after the specific audio tone sequences; or an emergency alert sent to predefined members of a PTT group, or a combination thereof.
