Push to Talk (PTT) (this service includes free instant messages)

Push to Talk is a National two-way radio service for businesses that prefer the stability of mobile phones instead of traditional two-way radio systems.


PTT utilizes national cell phone networks for communication. Similar to two-way radios, broadcasts can be made to everyone on the network, but with Push to Talk, users can now communicate one-on-one, one too many or in Broadcast Groups

Push-to-Talk allows instant voice communication to all mobile users on the network. This function allows staff to focus on the job at hand while being supported by highly stable, reliable and endless communication.

Instacom’s Push-to-Talk is a simple, yet effective application which can be incorporated into almost any modern day mobile smartphone. It therefore reduces the need for additional mobile radios should users already have a compatible handset. Instacom’s devices can also be utilised as regular mobile phones. There is no need to carry both a mobile phone and radio devices.

Push to Talk FAQ

  What is Push To Talk?


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.


  How does Push To Talk (PTT) work?


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.


  How will the Push To Solution save my business money?


Push to Talk can save your business money on communication costs and by driving business efficiencies. A Push to Talk solution can work out cheaper than alternative technology, such as 2-way radio, Trunking and portal phone (DECT) systems, as there is no need to pay the expensive licence, set up and hardware costs, it also utilizes existing mobile handsets and mobile tariffs and benefits from global coverage. Push to Talk can play a key part in workforce management and hence drive greater efficiencies to allow staffing and operational costs to be reduced.

  What is the benefit over my current radio system?


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.

Instacom’s “Push to” applications offer multiple communication applications in a single presence list. Members can be grouped into Push-to-Talk groups. The “buddy list” indicates the availability status of the members and allows users to not only PTT available members but also to send instant messages to the entire buddy list, single users or multiple users at once.
