Connecting Two Phones via Bluetooth for Calls: Is It Possible?

Can you connect two phones via Bluetooth to make calls? The answer is not straightforward and depends on the specific features and capabilities of the devices. In this article, we will explore the scenarios where Bluetooth can be used for making direct voice calls between two phones and the limitations of this feature.

Bluetooth Headset Scenario

If one of the phones is paired with a Bluetooth headset, it can be used to make calls while the headset is connected to it. This setup allows one phone to use the headset to make phone calls, essentially converting the headset into an extension of the phone's speaker and microphone. However, this does not enable direct voice calls between two phones.

Phone to Phone Direct Connection

Some advanced smartphones support features that allow them to connect directly via Bluetooth for specific functions. However, this does not include making voice calls between the two phones. Instead, Bluetooth is typically used for file sharing, data transfer, and other features. This method enhances the convenience and speed of data exchange but does not facilitate direct call connections.

Tethering Scenario

Another way to use Bluetooth to facilitate communication is through tethering. If one phone is connected to the internet, the second phone can access the internet via Bluetooth tethering. This setup might be useful for sharing an internet connection but will not create a direct call connection between the two phones. Tethering is more about sharing resources rather than enabling calls.

VoIP Apps Scenario

For direct voice calls between two phones, using VoIP apps like Skype or WhatsApp is a more reliable option. These applications enable phone-to-phone communication over the internet, bypassing traditional cellular networks for making voice calls. While this method does not utilize traditional Bluetooth for calls, it does provide a convenient way to communicate between phones.

Mixed Scenarios and Compatibility

While some models of Bluetooth headsets or hands-free devices support multiple simultaneous connections, they generally allow only one call to be answered at a time. This means that while multiple phones can be connected, only one can be used to accept calls, with others being put on hold. This limitation can be frustrating when trying to handle multiple calls through a single device, despite the possibility of connecting multiple units via Bluetooth.

It is important to note that while some manufacturers do offer devices with push-to-talk (PTT) functionality, this feature is usually limited to a single connection and is not a typical feature for dual phone calls via Bluetooth.

For direct voice calls between two phones, it is recommended to stick to traditional cellular networks or internet-based apps like VoIP applications for the best quality and reliability.
