Push To Talk (PTT) is a two way radio like service for businesses that uses GSM mobile phones instead of traditional 2-way radios or Two way radio users, looking for more stable and effective communication. Like a 2-way radio you can broadcast to everyone, but you can also talk privately on a one-to-one basis or to a small group of users. You can also use it as a regular mobile phone which avoids the need to carry a phone and a radio. Biggest advantages are virtually unlimited coverage, ease of use and no maintenance cost.

The Push To Talk (PTT) service uses the GSM mobile phone network rather than radio base stations. When a Push To Talk (PTT) call is made, instead of making a phone call, the voice message is transmitted over the phone's data channel direct to Instacoms Push To Talk (PTT) servers. The Instacom servers then forward the speech to the intended user or users, which results in the message being played out of the phone's loudspeaker. All of this happens without the need to answer the call which makes the communication much more immediate than a mobile phone call. Because the Instacom infrastructure is integrated into the SA's major mobile phone networks, it is possible to make and receive Push To Talk (PTT) calls Nationally.

The major benefit is service coverage. As Push To Talk (PTT) uses the global GSM mobile networks, the range of the service is restricted only by the coverage of the mobile phone networks, a range of approximately 90% (estimate)of the South Africa. PTT can also perform better than mobile phones during periods of heavy network congestion, for example during a large event or emergency situation. Unlike phone calls which are blocked when all the available voice channels in a cell are in use, Push To Talk (PTT) uses the data channel which slows down under congestion but is much more likely to remain available.
