Question

我有一个通过https://www.sip.us的免费演示SIP中继。我下载并配置了freeSWITCH，以允许使用SIP中继线对手机进行软件电话呼叫。我能够成功使用SIP中继线使用X-Lite软电话向手机进行出站呼叫。

但是，我的最终目标是成功地从服务器发送SIP邀请到移动电话，其唯一目的是从响应中提取包含IP地址的“ c = IN”头。所以我的问题是，我将如何发送SIP邀请（使用SIP中继）到手机并从c = IN字段提取IP地址？

我是SIP的新手，我甚至不确定我要执行的操作是否可行，但是我尝试了以下代码，最后一个console.log（res1）禁止输入403。我将以下npm模块https://github.com/kirm/sip.js用于代码：


    sipClient.send(invite, function(res) {

    var n_once = res.headers['proxy-authenticate'][0].nonce;


     var ctx = {};
     var authed = digest.signRequest(ctx,invite,res,{user: '5233339346',realm:'gw.sip.us' , password: 'serkrx44492qrb95'});

    console.log(authed.headers['proxy-authorization'][0].uri);
    authed.headers.via.pop();
    authed.headers['proxy-authorization'][0].uri = '"sip:+5233339346@gw.sip.us"';
    authed.headers.cseq.seq++;
    sipClient.destroy();
     sipClient = sip.create({
        port          : sourcePort,
        publicAddress : sourceIp,
        rport         : rport,
        tcp           : tcp,
        udp           : !tcp
    });

    sipClient.send(authed, function(res1) {
    console.log("**************************************************");
    console.log(sip.stringify(authed) + '\n');
    console.log("**************************************************");

    console.log("**************************************************");
    console.log(sip.stringify(res1) + '\n');
    console.log("**************************************************");


    sipClient.destroy();

    });
    });```

The initial request (invite) is as follows:

INVITE sip:+5205101984@174.18.53.9:5060 SIP/2.0
To: sip:+5205101984@174.18.53.9:5060
From: sip:+5233339346@gw.sip.us:6161;tag=568437
Call-ID: 568437
CSeq: 50452 INVITE
Content-Type: application/sdp
Contact: sip:+5233339346@gw.sip.us:6161
Max-Forwards: 70
Content-Length: 0

the response to that is as follows:

SIP/2.0 407 Proxy Authentication Required

Content-Length: 0

then I send the following:

INVITE sip:+5205101984@174.18.53.9:5060 SIP/2.0
To: sip:+5205101984@174.18.53.9:5060

Proxy-Authorization: Digest realm="gw.sip.us",username="5233339346",nonce="1eab4dfc-c06d-4a77-b1c1-7663196ef98a",uri="sip:+5233339346@gw.sip.us",nc=00000001,algorithm=md5,cnonce="0918657246a41f5577d7b334f793ca42",qop=auth,response="7c8cd15b73c69c4d1449242c81cc130e"

which then gives a 403 Forbidden response.
