Im using ejabberd + stanza.io to make a realtime messaging website, everything is working perfectly. now im willing to implement Webrtc audio/video using the jingle protocole. this is my JS code that i use to connect:

var client = XMPP.createClient({
  jid: xmpp_user+'@'+XMPP_DOMAIN,
  password: cu.auth.user_password,
  transport: 'websocket',
  wsURL: "ws://"+xms+":5280/websocket/"
});


client.jingle.config.debug = true;


client.on('session:started', function () {
  client.enableCarbons();
  client.getRoster(function (err, resp) {
    client.updateCaps();
    client.sendPresence({
      caps: client.disco.caps
    });
  });
});

client.connect();

the problem is when i call the user from an other app (AstraChat: iOS app that support Jingle) i get this in browser log:

Jingle: 67bzrsog243: session-initiate undefined undefined
Jingle: 67bzrsog243: Could not create WebRTC answer undefined undefined

this is the xml that astrachat is sending:

<iq xmlns='jabber:client' xml:lang='en' to='c4ca4238a0b923820dcc509a6f75849b@h2745110.stratoserver.net/352555070032013318140962' from='med@h2745110.stratoserver.net/AstraChat-iOS-21820150' type='get' id='3e8kjajc22'><query xmlns='http://jabber.org/protocol/disco#info'/></iq>

<r xmlns='urn:xmpp:sm:3'/>
Jingle: 3e8kjajc24: session-initiate undefined undefined
Could not create WebRTC answer undefined undefined

i really have no clue on how to fix that, any help will be appreciated.

根据您的日志，来自 Astra 聊天的会话发起是这样的： <iq xmlns="jabber:client" xml:lang="en" to="c4ca4238a0b923820dcc509a6f75849b@h2745110.stratoserver.net/352555070032013318140962" from="med@h2745110.stratoserver.net/AstraChat-iOS-21820150" type="set" id="3e8kjajc23"> <jingle xmlns="urn:xmpp:jingle:1" action="session-initiate" initiator="med@h2745110.stratoserver.net/AstraChat-iOS-21820150" responder="c4ca4238a0b923820dcc509a6f75849b@h2745110.stratoserver.net/352555070032013318140962" sid="3e8kjajc24"> <content creator="initiator" name="voice"> <description xmlns="urn:xmpp:jingle:apps:rtp:1" media="audio"> <payload-type id="101" name="speex" clockrate="8000" /> </description> <transport xmlns="urn:xmpp:jingle:transports:ice-udp:1" pwd="TC5NsD6IEQGXeDO8d5/3OU" ufrag="yA0z" /> </content> </jingle> </iq> 它仅提供 WebRTC 不支持的 speex 音频编解码器（opus 或 G.711 是强制性的）。WebRTC 中也没有强制加密。
