What Is Call Intercept? How Is It Different From Call Recording?

A call intercept is a technique using which one can invade an ongoing phone call and listen to someone’s conversation while it’s happening. In the earlier days, a bug used to be fixed in the landlines to intercept calls on it. However, in the modern era, you just need to install an interceptor app on the target phone and you can remotely listen to all the ongoing calls on it.

If you are constantly looking to spy on someone’s phone calls then you must have come across two terms; call intercept and call recording. Well, a call intercept is what we already discussed is a technology that allows you to listen to a live call that is happening in real-time. Whereas a call recording is where you listen to a recorded phone call remotely i.e. it is not an ongoing call, it’s a phone call that has already happened and you are listening to it later.

The benefit of call intercepting over call recording is that you can take urgent action in case there is something serious being discussed over the call.

How To Intercept Someone’s Phone Calls?

As I told you earlier, these days you can intercept a phone call from another phone using special apps. One of the best phone call interceptor apps that you can use is FlexiSPY.

Things To Know:

1. You need to have physical access to the target phone to install the FlexiSPY app on it. To listen to an incoming or outgoing call on a phone you need to install FlexiSPY on it and for that, you need to have the device in your hand. Don’t worry the app works in hidden mode. So once it is installed, the target person will never know about it. You can get access to the target phone when the phone’s owner is not around, the installation won’t take more than 5 minutes so you can easily install the app.

2. The target phone needs to be rooted or jailbroken. The call intercept feature of FlexiSPY only works on rooted or jailbroken phones. So if the target phone is already rooted then well and good and if it is not then you can root or jailbreak it before installing the FlexiSPY app on it. Don’t worry if you have no experience with rooting or jailbreaking then you can take the help of  FlexiSPY customer support, they will help you with that.

What’s even better is you can order a rooted Android or jailbroken iPhone with FlexiSPY preinstalled on it using the FlexiSPY EXPRESS service. If you are looking to gift your kids or spouse a new phone then you can purchase it from FlexiSPY EXPRESS and be worry-free about their safety online.

3. You need to set a Monitor Number. A monitor number is the phone number that is used to intercept the phone call. It is the number on which you will receive an SMS alert whenever the target person is on a call. The monitor number can be your personal number or you can purchase a new SIM for this purpose.


First of all, you need to install the FlexiSPY app on the target phone. You can follow the installation steps shared in our FlexiSPY review. If you have bought the phone from FlexiSPY Express then you don’t need to install the FlexiSPY app on it because it comes preinstalled with it.

Now for the call interception feature to work properly, you need to follow these steps.

1. Go to your FlexiSPY dashboard and then select the Live Listening option and then click on Enable Live Listening.

After setting up the Monitor Number, go back to the Enable Live Listening tab and toggle on the Live Listening button.

4. Now the Watch List option will appear under the Live Listening option. Click on Watch List, and now choose the options as per your convenience to intercept the calls on the target phone. The options are as follows:

  • Intercept all unknown calls
  • Intercept all calls in the target phone’s address book
  • Intercept all calls, not in the target phone’s address book

You can select one or more than one of these options. You can also add up to 10 numbers of your choice to complete the watchlist. After creating your watchlist, save your changes and you are good to go.

After you have successfully enabled live listening on FlexiSPY, you can now listen to all the calls made or received from the numbers that are on the watchlist. Here’s how it works.

  • You will receive an SMS on the monitor number whenever the target person is on the call with someone from the watchlist.

  • Once you get the SMS, you need to call the target phone’s cell number from the monitor number to intercept the ongoing call. Make sure while doing this you mute the monitor phone’s mic. Otherwise, they will get suspicious by listening to your background noises.
