BSNL may soon bring a major convenience feature for millions of users across India. The state-run telecom operator is reportedly working on integrating CNAP, or Caller Name Presentation, into its network. Once rolled out, the feature will allow users to see the caller’s name directly on incoming calls, even without using third-party apps like Truecaller.
Private telecom operators such as Reliance Jio, Bharti Airtel, and Vodafone Idea have already started implementing the feature. Now, BSNL appears to be moving closer to a nationwide rollout.
What Is CNAP Feature
More Read
CNAP stands for Caller Name Presentation. It is an initiative introduced by the Telecom Regulatory Authority of India to help users identify unknown callers before answering calls. The feature works differently from apps like Truecaller. Instead of relying on crowd-sourced data or internet access, CNAP uses KYC-verified subscriber information stored with telecom operators.
This means users can see the caller’s registered name directly through their telecom network without downloading any additional application.
How CNAP Works
The system is designed to display the caller’s name automatically during incoming calls.
Some key highlights include:
- No internet connection required
- No third-party app installation needed
- Uses KYC-verified subscriber details
- Works directly through telecom networks
- Aims to reduce spam and fraud calls
This makes the feature more reliable and secure compared to app-based caller identification systems.
BSNL Reportedly Testing Integration
According to reports, BSNL has already deployed the CNAP solution internally and is currently working on integrating it with private telecom operators.
The integration is reportedly happening zone by zone across the country. Industry sources claim that cross-network testing is underway to ensure the feature works smoothly between different telecom providers.
An industry executive familiar with the development reportedly stated that Jio, Airtel, and Vodafone Idea had already implemented the system earlier, while BSNL’s integration process is currently ongoing.
Nationwide Rollout Expected Soon
Reports suggest that BSNL may launch the feature nationwide within the next three to four months once integration testing is completed.
The CNAP solution for BSNL has reportedly been developed and implemented by the Centre for Development of Telematics, commonly known as C-DoT.
If the rollout happens as expected, BSNL users across India could soon get native caller ID functionality without depending on external services.
Why This Feature Matters
Spam calls and scam attempts have become a major issue for mobile users in India. Unknown calls often create confusion, and many people hesitate before answering important calls.
CNAP aims to solve this problem by giving users more clarity.
Some major advantages include:
- Better identification of unknown callers
- Reduced dependence on third-party apps
- Improved protection against spam and fraud
- Faster decision-making before answering calls
- More trust in telecom-based caller information
Since the feature uses verified subscriber details, it could also improve authenticity compared to crowd-sourced databases.
Current Limitations Of CNAP
Although the feature has already started rolling out in phases, there are still some limitations.
At present, CNAP works more reliably when both the caller and receiver are on the same telecom network. Cross-network compatibility remains one of the biggest technical challenges.
Telecom operators are still working to improve interoperability between different networks.
Another limitation is that the feature is not available on feature phones. It is mainly designed for supported smartphones running on compatible 4G and 5G networks.
TRAI And DoT’s Role
The CNAP initiative was introduced in the second half of 2025 as part of broader efforts to tackle spam calls and improve caller transparency.
The Department of Telecommunications had also conducted trial runs on both 4G and 5G networks before the feature’s phased rollout began.
The idea behind the system is to provide a telecom-native caller identification solution that works without internet dependency.
What Users Can Expect
Once fully rolled out, BSNL subscribers are expected to receive caller name details automatically during incoming calls.
Users will not have to:
- Pay extra subscription fees
- Install third-party apps
- Share personal data with external services
The feature is expected to become a built-in telecom-level service.
Conclusion
BSNL’s upcoming CNAP rollout could become a major upgrade for users across India. With spam calls and fraud attempts increasing rapidly, telecom-based caller identification feels more relevant than ever.
The biggest advantage of CNAP is simplicity. It works directly through the network using verified subscriber information, without needing internet access or additional apps.
While cross-network compatibility challenges still exist, the nationwide rollout expected in the coming months could make caller identification more seamless and secure for millions of BSNL users.
