There are things that a professional push-to-talk app just has to deliver, but a generic PTT app cannot. When choosing a PTT app for professional use, what should you look for? We look at 12 must-haves for a professional PTT app.

When an app offers Push-to-talk, or PTT, the speaker simply presses the PTT key to talk to the group - the key needs to be kept pressed while they are speaking. On a PMR radio, PTT is the best way to connect a group of people who need to work together.

You have most likely seen PTT applications claiming to “turn your smartphone into a walkie-talkie”. These generic PTT apps seem to promise much - near-instant communications with a push of a button, group calling, and even priorities and emergency calls. Yet, they actually deliver very little, certainly nowhere near what a professional user needs.

Make sure you get an app that really delivers on the key requirements and lets you do these 12 vital things!

Download a handy checklist which helps you identify the push-to-talk app that meets your professional requirements:


12 vital capabilities for professional use

1. Talk to a group of employees without looking at the device: Your finger should find the PTT button easily, even when your eyes are on the action. It should also be easy to keep it pressed for as long as you need it.


2. Instant connection: A split-second call setup time is needed - typically less than 0.3 seconds. Any longer than that, and the beginning of your sentence could be cut off. Just think about the difference between “Don’t start the engines” and “- start the engines”!

3. Keep your place in the queue: If you can’t speak straight away because someone else is speaking, you need an app that lets you queue for your turn to speak.

4. Talk to one person as well: A professional push-to-talk app will allow you to PTT call a single person (with an individual or one-to-one call). You don’t want to have to close the app to make a phone call.

5. Make sure you don’t miss important communications: There’s another drawback if you can’t make a one-to-one call within the PTT app - while you are on the phone, you will miss the communications going on in the group. Your best choice would be a push-to-talk app which not only lets you make a one-to-one call, but can also invite you to a group call so you don’t miss a thing.

6. Make double sure you don’t miss important communications: The so-called Late Entry feature is a must. It means that a user who has just switched on the device, or has just finished another call will be invited into an ongoing group call if he/she is a member of that group.

7. Get help – fast: If your work takes place in a high-risk area , you need a PTT app that lets you make an emergency call to get help very quickly. But, make sure it won’t let you make one accidentally.

8. Does the PTT app include an emergency call or a “red key call”? Then check it also meets the following criteria:

9. You shouldn’t have to select a number to call in an emergency – not even 112 or 911. The app should automatically send the call to the right place.

10. The app should allow the emergency call to go anywhere that your organization needs it to go - to your site manager, your teammate, or a group of people. And, if your first choice of recipient doesn’t answer, will the call go to someone else? It should!

11. Do more than talk: Push-to-talk is mostly associated with speaking, but can the PTT app deliver more? Can you easily send messages with pictures, attached documents and video clips or even stream video within the app, for example? To the same groups that you speak to, or to individuals?

12. Keep track of where you are: Can the PTT app track the device’s location? This feature puts the location on the screen of a dispatching application, keeping you and other users safer.

How to make sure your PTT app works as needed

To gain the full capabilities of a professional PTT technology, a number of key requirements need to be met.

Security and control

In critical operations, security can never be compromised. It is the first priority throughout the service lifecycle – from the early design phases and development to validation, audits and regular security tests.

Setting up the PTT application needs to be professionally managed. You need to adopt apps in a controlled and systematic way. This way, the app won’t be a novelty used only by a few staff instead, it can support the goals of your whole organization. Even when opting for controlled adoption, you should prefer an app that is easy to set up in your devices. Set-up over a remote connection will make your life a lot easier!

Managed groups

For smooth communication in working teams, you need talk groups. Once again, ad hoc groups are fine for off duty time, but professionals need a controlled solution. If users can set up their talk (chat) groups themselves, one mis-typed phone number could mean the group communications becoming open to outsiders.

Add-on 1: Join PMR/LMR group calls with your smartphone PTT app

Does your organization need the PTT apps to work with radio communications? It can be done. Smartphones with the PTT app can join the established PMR/LMR groups for easy, yet controlled communication.

Add-on 2: Use the PTT app seamlessly with TETRA

Ideally, smartphones with the PTT app are able to join the same established TETRA groups that are used in TETRA radios. Users can rely on easy and secure communication both with TETRA radio and smartphone users as well as with the control room. Not to mention that the PTT app can also offer many other reliable TETRA features to your smartphone.

In other words, people vital to an operation would be connected easily and securely, even when they are using different devices and technologies in a hybrid TETRA and broadband environment.
