是否可以发送DTMF音频在安卓活动的呼叫?我尝试着用 proxyphone.sendDtmf()
,但它是没有用的。
Is it possible to send DTMF tones in active call in android ? I tried it with proxyphone.sendDtmf()
but it was useless.
我怎样才能实现呢?
在VOIP只有它是可能的,Android应用程序都将在通话音频流进行访问。你可以伪造一个它的免提模式了一下。
In VOIP only it is possible,Android applications have no access to the in-call audio stream. You can fake a it a bit in speakerphone mode.
