What is PTT (Push-To-Talk)?

PTT means Push-To-Talk which is a two-way correspondence benefit which works like a “walkie-talkie”. PTT is half-duplex so correspondence must be moved one way at once rather than mobile telephone calls which are full-duplex and the two gatherings can hear one another.

PTT requires the individual speaking to press a certain catch while talking and to discharge it when they are done as such the listener can reply by repeating similar advances. Thusly individuals control which one can talk and be heard and the system knows in which heading the information ought to be exchanged.

Most PTT systems allow group calls (one individual addresses every one of the individuals from the group). The most up to date PTT systems use VoIP innovation and the signal is exchanged over the 2.5G or 3G network.
