Caller Name for VOIP implementation

I've been told that it's not possible to get the incoming caller's name with an IoT modems. I figured this would be a standard feature if using the modem for a VOIP solution. Is this in fact a limitation of IoT modems? Are they truly that different from phone modems in the way they handle calls? How would I be able to see the incoming SIP INVITE from the carrier? Is it possible with these modems?

IoT (Internet of Things) modems, particularly those used for VoIP (Voice over Internet Protocol) solutions, can indeed vary in their capabilities compared to traditional phone modems. Whether or not you can retrieve the incoming caller's name depends on various factors including the specific modem you're using, the VoIP service provider, and the features they support.
 
Here are some points to consider:
 
1. Modem Capabilities: Some IoT modems may have limited capabilities compared to traditional phone modems. They may prioritize data transmission over voice features, and thus lack certain functionalities like caller ID name display.
 
2. VoIP Service Provider Features: The ability to retrieve the incoming caller's name often depends on the features provided by your VoIP service provider. Some providers offer caller ID name display as part of their service, while others may not support this feature or may require additional configuration.
 
3. SIP INVITE Inspection: If you want to inspect the SIP INVITE message from the carrier to extract caller information, it's technically possible with the right setup. You would need to intercept and analyze the SIP signaling traffic between your modem and the VoIP carrier. However, this typically requires more advanced networking knowledge and may not be supported by all modems or carriers.
 
4. Configuration and Integration: Even if your modem supports receiving caller ID information, you may need to configure it properly to enable this feature. This could involve settings within the modem itself or configuration on your VoIP service provider's platform.
 
5. Compatibility and Standards: Ensure that your modem and VoIP service provider comply with relevant standards for caller ID information exchange (such as SIP standards). If there are discrepancies in implementation or compatibility issues, it could affect the visibility of caller information.
 
In summary, while it's technically possible to retrieve incoming caller information with IoT modems used for VoIP solutions, it depends on various factors including modem capabilities, VoIP service provider features, configuration settings, and technical know-how. If caller ID name display is crucial for your application, it's worth checking with your VoIP service provider and modem manufacturer to determine the feasibility and requirements for enabling this feature.
