在Android中接收DTMF
[英]Receiving DTMF in Android
问题描述
Wanted to know if there is a way to decode the DTMF signals (sent from other phones) into numbers so that the number can be manipulated as required? 
想知道是否有办法将DTMF信号（从其他电话发送）解码为数字，以便可以根据需要操作数字？
For eg: If I am pressing 1234 from phone A during a call I should be able to get that 1234 number on the Android phone B. 例如：如果我在通话期间从电话A按1234，我应该可以在Android手机B上获得1234号码。

As far as I know this is not supported yet. 据我所知，这还不支持 。
You can't tap into the voice call sound stream, so there is no way you can detect DTMF tones by yourself even if you wanted to. 您无法接入语音呼叫声音流，因此即使您愿意也无法自己检测DTMF音频。
