Spam Calls and Caller ID Issues

Spam calls and Caller ID issues are common problems that affect mobile devices and VoIP systems. This article covers how spam detection works, how to manage your Caller ID in the net2phone SONAR portal, and what to do if you suspect fraud.

How Spam Detection Works

Your mobile device and carriers use a combination of machine learning, network analysis, and user reports to identify and flag suspicious calls. Here's how your phone might detect spam:

Caller ID Authentication
Verifies that the displayed phone number matches the one making the call.

Call Frequency
Frequent or short-duration calls from the same number may trigger spam warnings.

Geographic Origin
Calls from locations associated with fraud may be flagged.

User Reports
Reports from other users help phones recognize and block spam calls.

iPhone and Android Anti-Spam Features 

Both iPhone and Android devices offer built-in features to identify and block suspected spam calls.

Caller ID Issues

If your Caller ID is not displaying correctly through the net2phone Canada system, it may be due to the following:

Carrier Delays
Carriers may take up to 60 days to update their databases when a new number is acquired, causing incorrect Caller ID display.

Hardware Settings
Some devices may have local scanning features affecting Caller ID presentation.

How to Check and Update Caller ID in Sonar

If you are an Office Manager, follow these steps to verify or update your Caller ID.

  1. Log in to the Sonar portal with Office Manager credentials.
  2. Navigate to the Users tab.
  3. Find the user you want to view, and click their name. 
  4. Within the Profile subtab, scroll down to the Caller ID section

If you’re checking another user’s Caller ID, refer to the Managing Users guide for details.

Troubleshooting Caller ID and Fraudulent Calls

If your number is flagged as fraudulent, carriers may block it from accessing the Public Switched Telephone Network (PSTN). When this happens, calls to your number will result in a fast-busy signal.

If you're experiencing Caller ID issues:

  1. Confirm the number is saved correctly on the recipient’s device.
  2. Check your Sonar Portal to ensure the Caller ID is properly set.
  3. If the issue persists, it may be a carrier database delay. You can contact net2phone support to verify if we are sending the correct Caller ID.
