node.js - SIP Redirect via Proxy (SIP.js) -

-

i'm trying create minimal sip proxy serves 1 purpose: redirects requests domain. catch domain i'm redirecting requires authorization assume need rewrite sip attributes since sip authorization based partly on domain name of destination.

i've tried issuing 302 redirect proxying , changing values of each sip request none seem quit trick. i'm using node.js library (sip.js) , have tried redirect , proxy modules (https://github.com/kirm/sip.js/blob/master/doc/api.markdown).

any ideas how need modify sip data redirect requests domain , enable authentication take place against other domain?

below basic node script got working own sip server. you'll need replace credentials , ip address fro own testing.

the proxy script not send redirect response client instead initiates new transaction server on client's behalf. sip server operating in mode more correctly called back-to-back user agent (b2bua). haven't added functionality needed, such matching , passing responses original client; there fair bit of work involved in that.

var sip = require('sip'); var digest = require('sip/digest'); var util = require('util'); var os = require('os'); var proxy = require('sip/proxy');  var registry = {   'user': { user: "user", password: "password", realm: "sipserver.com"}, };  function rstring() { return math.floor(math.random()*1e6).tostring(); }  sip.start({   address: "192.168.33.116", // if ip not specified here proxy uses hostname in via header causes issue if it's not qualified.   logger: {      send: function(message, address) { debugger; util.debug("send\n" + util.inspect(message, false, null)); },     recv: function(message, address) { debugger; util.debug("recv\n" + util.inspect(message, false, null)); }   } }, function(rq) {   try {     if(rq.method === 'invite') {           proxy.send(sip.makeresponse(rq, 100, 'trying'));        //looking user info       var username = sip.parseuri(rq.headers.to.uri).user;           var creds = registry[username];        if(!creds) {           proxy.send(sip.makeresponse(rq, 404, 'user not found'));       }       else {         proxy.send(rq, function(rs) {              if(rs.status === 401) {                  // update original request it's not treated duplicate.                 rq.headers['cseq'].seq++;                 rq.headers.via.shift ();                 rq.headers['call-id'] = rstring();                  digest.signrequest(creds, rq, rs, creds);                  proxy.send(rq);             }         });       }     }     else {       proxy.send(sip.makeresponse(rq, 405, 'method not allowed'));     }   } catch(e) {     util.debug(e);     util.debug(e.stack);     proxy.send(sip.makeresponse(rq, 500, "server internal error"));   } });
