In our daily life, someone might borrow our mobile phone to make a phone call, then we have to give our phone to him until he is finished the call.

Outgoing phone call transfer agent based on Bluetooth

Outgoing call transfer from a Bluetooth device to target phone, require 3 participators: the calling Bluetooth device A, a smart phone B and the target phone C. A doesn't need to access the cellular network, but Bluetooth connection is necessary. B must be a smart phone that install a extended dial application and a voice recognition module. C is a normal cell phone or telephone landline.



Before the process, A need to connect with B via Bluetooth. If A is also a smart phone, then A could use the extended dial application to send the calling request to B. If A is not a smart phone, but only a normal Bluetooth device, then A can send the calling request to B, then the voice recognition module of B can analyze the request and proceed the calling to C.

After B calling to C, C will answer B, and start the conversation, but B will not involve in this conversation. B will directly transfer the voice message between A and C.

To end the conversation, A, B or C can do it. If anyone of them stop the session, then conversation is ended.

There are 2 methods to implement the idea: Method 1: Extend the existing dial application, after BT connection between A and B, long press dial button will show the choice of calling C by B.

Method 2: A is not a smart phone, just a normal Bluetooth device that can receive and send voice message. Then after A connect with B via Bluetooth, A can send voice message to B in order to call C.
