Have you ever been reluctant to call someone because you were unsure if they were in a meeting or busy? Or have you ever contacted someone only to be put on hold or, worse, have your call go directly to voicemail? Uncertain if the person on the other end is available or busy is something we’ve all experienced. Knowing if someone is busy before making a call would be fantastic, wouldn’t it? Let’s investigate various ways to determine whether a number is busy without making a phone call.
Method 1: Using Truecaller App
The Truecaller software allows you to determine whether a number is busy without actually calling that number. Here’s how:
👉 Requirements:
1. Truecaller app installation: Install the Truecaller app on your Android or iOS device.

2. The other person’s Truecaller usage: Additionally, the person you are attempting to reach must have Truecaller installed on their device.
3. Data connection: In order for Truecaller to update the user’s status, their device has to have an active data connection (such as Wi-Fi or mobile data).
⭐Steps:
Step 1: Open the Truecaller app on your device.
Step 2: Search for the person’s phone number in the Truecaller database.

Step 3: You will see the person’s status update if they have Truecaller installed and an active data connection.

Step 4: Any state, including Last Seen, Available, On a call, and Silent, will be visible to you. Checking the other person’s state is now necessary: If it reads “On a Call,” the person is probably occupied with another call.

🔴 Limitations:
1. Truecaller usage: This technique is only effective if the user has Truecaller installed and is utilizing it.
2. Data connection: In order for the person’s status to be updated, their device needs to have an active data connection.
3. Status accuracy: Truecaller may not always provide accurate or current status updates.
Without actually calling the person’s number, you can use Truecaller to find out if they are occupied with another call.
Method 2: Using Voice Over IP (SIP) Phone
Without actually calling a number, you can use a Voice Over IP (SIP) phone to see if it is busy. Here’s how:
Step 1: Configure your SIP phone: Create a useless SDP (Session Description Protocol) setting for your SIP phone.
Step 2: Send a connection request: Make a connection request to the number you wish to verify.
Step 3: Analyze the response: The request will fail differently if the line is engaged than if it is open but the SDP negotiation was unsuccessful.
The recipient might still be notified of the attempted contact, thus this approach might not be perfect.
Method 3: Using Skype
You can use Skype to check if a number is busy without revealing your caller ID. Here’s how:
Step 1: Use Skype’s “Call Phone” feature: Use Skype’s “Call Phone” feature to call the number you want to check.

Step 2: Use Skype credits: Make sure you have Skype credits to make the call.
Step 3: Skype will display a random number: Skype will display a random number (e.g., +3345 or +334) instead of your Skype ID or caller ID.
⚠️ Note: This method requires Skype credits and may not work if the recipient has caller ID blocking or other call screening features enabled.
