1.安装swigwin-4.0.1 下载地址http://www.swig.org/download.html 注意是swigwin

Windows users should download swigwin-4.0.1 which includes a prebuilt executable. 

配置目录到win path

2.下载pjproject-2.10.zip(如果有python错误请安装py2.7 及环境path配置)

使用vs pjproject-vs14.sln 打开 重定向资源方案

>配置jdk的include 目录到swig_java_pjsua2 （属性->c/c++->附件库目录）添加D:\\java\\jdk1.8\\jdk1.8\\include及D:\\java\\jdk1.8\\jdk1.8\\include\\win32

 >在swig_java_pjsua2项目点击生成  如果遇到错误pj/config_site.h 没找到  双击 用//注释  没用到视频的没用

最后成功后在\pjproject-2.10\pjsip-apps\src\swig\java\output目录有pjsua2.dll 

及org.pjsip.pjsua2 的java 类 及上级目录官方java demo

3.创建一个java 工程写入代码

package com.test;
import java.io.IOException;

import org.pjsip.pjsua2.*; //上面目录copy

//Subclass to extend the Account and get notifications etc.
class MyAccount extends Account {
@Override
public void onRegState(OnRegStateParam prm) {
System.out.println("*** On registration state: " + prm.getCode() + prm.getReason());
}
}

class MyCall extends Call{

    public MyCall(Account acc, int call_id) {
super(acc, call_id);

// TODO Auto-generated constructor stub
}

    @Override
public void onCallState(OnCallStateParam prm)
{
try {
CallInfo ci = getInfo();
System.err.println( ">>>>>>>>>>>"+ci.getStateText());    
} catch (Exception e) {
}

        // Should not delete this call instance (self) in this context,
// so the observer should manage this call instance deletion
// out of this callback context.

}

    @Override
public void onCallMediaState(OnCallMediaStateParam prm)
{
CallInfo ci;
try {
ci = getInfo();
} catch (Exception e) {
return;
}

        CallMediaInfoVector cmiv = ci.getMedia();

        for (int i = 0; i < cmiv.size(); i++) {
CallMediaInfo cmi = cmiv.get(i);
if (cmi.getType() == pjmedia_type.PJMEDIA_TYPE_AUDIO &&
(cmi.getStatus() ==  pjsua_call_media_status.PJSUA_CALL_MEDIA_ACTIVE ||
cmi.getStatus() ==   pjsua_call_media_status.PJSUA_CALL_MEDIA_REMOTE_HOLD))
{
// unfortunately, on Java too, the returned Media cannot be
// downcasted to AudioMedia

Media m = getMedia(i);
AudioMedia am = AudioMedia.typecastFromMedia(m);
System.err.println( ">>>>>>>>>>>");    
// connect ports
try {
Test.ep.audDevManager().getCaptureDevMedia().    startTransmit(am);
am.startTransmit(Test.ep.audDevManager(). getPlaybackDevMedia());
} catch (Exception e) {
continue;
}
} else if (cmi.getType() == pjmedia_type.PJMEDIA_TYPE_VIDEO &&
cmi.getStatus() ==
pjsua_call_media_status.PJSUA_CALL_MEDIA_ACTIVE &&
cmi.getVideoIncomingWindowId() != pjsua2.INVALID_ID)
{
// vidWin = new VideoWindow(cmi.getVideoIncomingWindowId());
//vidPrev = new VideoPreview(cmi.getVideoCapDev());

            }
}

}


}

public class Test {

System.load("C:/Users/lilin/Desktop/v2.10pjsua2.dll");//上面目录pjsua2.dll
System.out.println("Library loaded");
}
static Endpoint ep = new Endpoint();
public static void main(String argv[]) {
try {

// Initialize endpoint

ep.libInit( epConfig );
// Create SIP transport. Error handling sample is shown

sipTpConfig.setPort(5060);
ep.transportCreate(pjsip_transport_type_e.PJSIP_TRANSPORT_UDP, sipTpConfig);
// Start the library
ep.libStart();

       AccountConfig acfg = new AccountConfig();
acfg.setIdUri("sip:1010@ip:5060");
acfg.getRegConfig().setRegistrarUri("sip:ip:5060");
AuthCredInfo cred = new AuthCredInfo("digest", "*", "1010", 0, "h1234");
acfg.getSipConfig().getAuthCreds().add( cred );
// Create the account
MyAccount acc = new MyAccount();
acc.create(acfg);

System.out.println("=====end====");
// Here we don't have anything else to do..
Thread.sleep(2000);


MyCall my = new MyCall(acc, -1);
CallOpParam prm = new CallOpParam(true );
my.makeCall("sip:1005@ip:5060",  prm);

while (true){
Thread.sleep(1000);


}

/* Explicitly delete the account.
* This is to avoid GC to delete the endpoint first before deleting
* the account.
*/
//acc.delete();

       // Explicitly destroy and delete endpoint
//  ep.libDestroy();
//ep.delete();

   } catch (Exception e) {
System.out.println(e);
return;
}
}
}

好了   以上就是一个呼叫过程了  成功后就可以和其他的sip 软件呼叫了 也可以去实现视频
