Java代码实现SIP通话-Toy模板网

这篇具有很好参考价值的文章主要介绍了Java代码实现SIP通话。希望对大家有所帮助。如果存在错误或未考虑完全的地方，请大家不吝赐教，您也可以点击"举报违法"按钮提交疑问。

在 Java 中实现 SIP 通话可以使用 SIP API，比如 SIP API for Java (SIPServer API) 或者 MJSip。

使用 SIP API for Java (SIPServer API) 可以这样写代码：

``` import java.io.IOException; import java.net.InetAddress; import javax.sip.ClientTransaction; import javax.sip.Dialog; import javax.sip.DialogState; import javax.sip.DialogTerminatedEvent; import javax.sip.IOExceptionEvent; import javax.sip.ListeningPoint; import javax.sip.RequestEvent; import javax.sip.ResponseEvent; import javax.sip.ServerTransaction; import javax.sip.SipFactory; import javax.sip.SipListener; import javax.sip.SipProvider; import javax.sip.SipStack; import javax.sip.TimeoutEvent; import javax.sip.TransactionTerminatedEvent; import javax.sip.address.Address; import javax.sip.address.AddressFactory; import javax.sip.address.SipURI; import javax.sip.header.CSeqHeader; import javax.sip.header.CallIdHeader; import javax.sip.header.ContactHeader; import javax.sip.header.ContentTypeHeader; import javax.sip.header.FromHeader; import javax.sip.header.HeaderFactory; import javax.sip.header.MaxForwardsHeader; import javax.sip.header.ToHeader; import javax.sip.header.ViaHeader; import javax.sip.message.MessageFactory; import javax.sip.message.Request; import javax.sip.message.Response;

public class SIPClient implements SipListener { private static SipStack sipStack; private static SipProvider sipProvider; private static AddressFactory addressFactory; private static MessageFactory messageFactory; private static HeaderFactory headerFactory; private static ListeningPoint listeningPoint; private static SipFactory sipFactory; private static Dialog dialog;文章来源地址https://www.toymoban.com/news/detail-562294.html

public static void main(String[] args) {
    SIPClient sipClient = new SIPClient();
    sipClient.init();
    sipClient.sendInvite();
}

public void init() {
    sipFactory = SipFactory.getInstance();
    sipFactory.setPathName("gov.nist");
    Properties properties = new Properties();
    properties.setProperty("javax.sip.STACK_NAME", "SIPClient");
    try {
        // Create SipStack object
        sipStack = sipFactory.createSipStack(properties);
        System.out.println("createSipStack " + sipStack);
    } catch (PeerUnavailableException e) {
