My Android advanced tour ------> four call transfer scenarios, android advanced

The operator provides the following call transfer scenarios:

1. Always call transfer: No matter what status the current mobile phone is in, incoming calls will be transferred to the specified phone number. You should be very careful when using this type of call transfer. If this type of call transfer is enabled, you will never be able to receive the call, and your mobile phone will not respond.

2. Call Transfer When busy: This call transfer method is very useful. For example, if a salesperson has a large business volume and has another landline around him, set the call transfer number to the landline number. In this way, an incoming call occurs when you use a mobile phone to answer the call or make a call. The incoming call is directly transferred to the landline so that important calls are not missed. This call transfer method also performs call transfer when the call is rejected. Therefore, you can use this call transfer method to implement the call interception function. That is to say, when a call is sent, the application will immediately stop the call. This is based on the set transfer phone number, the recipient will hear four types of voice replies: "The phone has been stopped", "The phone has been shut down", "the phone number is empty", and "The phone number is in the middle of the call.

3. Call Transfer when no response is received: if the call is not answered for some reason, the call is interrupted after a certain period of time.

4. Call Transfer when the connection fails: Call Transfer is performed when the signal is not on the server, there is no signal or shutdown.

All the above four call transfer methods have their corresponding special numbers. In addition, you can use a special number to cancel call transfer and query whether a call transfer is enabled. The special numbers corresponding to the above four call transfer methods are as follows:

Function	Set	Cancel	Query
Always call transfer	** 21 * phone number #	#21 #	* #21 #
Call Transfer When busy	** 67 * phone number #	#67 #	* #67 #
Call Transfer when no response is received	** 61 * phone number #	#61 #	* #61 #
Call Transfer when the connection fails	** 62 * phone number #	#62 #	* #62 #

The code for setting the call transfer number when the line is busy is as follows:

Intent callIntent=new Intent(Intent.ACTION_CALL,Uri.parse(Uri.encode("tel:**67*12345678910#")));startActivity(callIntent);

The code for calling the transfer number when the line is canceled is as follows:

Intent callIntent=new Intent(Intent.ACTION_CALL,Uri.parse(Uri.encode("tel:##67#")));startActivity(callIntent);

The code for querying the call transfer number when the line is busy is as follows:

Intent callIntent=new Intent(Intent.ACTION_CALL,Uri.parse(Uri.encode("tel:*#67#")));startActivity(callIntent);
