我正在为Android开发SIP客户端并且有问题。问题是我连接两个客户端时没有音频。我正在使用的服务器是www.minisipserver.com。每次调用SipAudioCall.Listener中的onCallEstablished方法。
这是扩展BroadcastReceiver的类，它正在侦听调用。 `

SipAudioCall incomingCall = null;
try {
Call callActivity = (Call) context;
SipAudioCall.Listener listener = new myListener(context);
incomingCall = callActivity.mManager.takeAudioCall(intent, listener);
incomingCall.startAudio();
callActivity.mAudioCall = incomingCall;
callActivity.updateStatus(incomingCall);
} catch (SipException e) {
if (incomingCall != null) {
incomingCall.close();
e.printStackTrace();
}
}
}
class myListener extends SipAudioCall.Listener {

public myListener(Context context) {
this.context = context;
}

您使用什么库进行SIP信令？
在某些图书馆中，您必须在建立时将麦克风和扬声器分配给通话。
