ABSTRACT

PTT (Push-to-talk) is one of the most common methods for Public Safety communications. Modern smart phones normally have a touch screen (either capacitive or resistive) that is used to work with applications installed on the device. This screen is used to start and stop PTT call with favorite contact.
