使用基於sip.js的webrtc應用程序和星號11.11.0，Chrome沒有音頻。 與Firefox和Opera正常工作

Question

我正在使用sip.js和星號開發webrtc。 我的webrtc應用程序在Firefox 31和Opera 22.0.1471.70上運行良好。 但是，當我將我的webrtc應用程序與chrome一起使用時（版本37.0.2062.58 beta-m（64位））。 一切似乎都很好，但是沒有音頻。 我還嘗試了最新穩定的Chrome瀏覽器的32版本。 問題保持不變。

Setup Details:-

1. Asterisk 32 bit - 11.11.0
2. Sip-0.6.1.js 
3. Chrome (Version 37.0.2062.58 beta-m (64-bit)), Firefox 31.0 and opera 22.0.1471.70.
4. Cent O.S 6.5 (32 bit)

星號配置：

host=dynamic
secret=password
context=default


[1090] ; This will be WebRTC client
type=friend
username=1090 ; The Auth user for SIP.js

icesupport=yes ; Tell Asterisk to use ICE for this peer
context=default ; Tell Asterisk which context to use when this peer is dialing
directmedia=no ; Asterisk will relay media for this peer
transport=udp,ws ; Asterisk will allow this peer to register on UDP or WebSockets
force_avp=yes ; Force Asterisk to use avp. Introduced in Asterisk 11.11
dtlsenable=yes ; Tell Asterisk to enable DTLS for this peer
dtlsverify=no ; Tell Asterisk to not verify your DTLS certs

dtlssetup=actpass ; Tell Asterisk to use actpass SDP parameter when setting up DTLS
nat=no
disallow=all
allow=ulaw

extension.conf 
[default]
exten => 1060,1,Dial(SIP/1060) ; Dialing 1060 will call the SIP client registered to 1060
exten => 1061,1,Dial(SIP/1061) ; Dialing 1061 will call the SIP client registered to 1061

call.js code:-

( function()
  {
     var session;

     var endButton = document.getElementById('endCall');

     endButton.addEventListener("click", function ()
                                         {
                                            session.bye();
                                            alert ("Call Terminated");
                                         }
                                       , false
                               );


     //Registration and websocket connectivity details for the useragent

     var config = {

                        // Asterisk IP address,

     //Creates the anonymous user agent so that you can make calls
     var userAgent = new SIP.UA (config);

    //Here you determine whether the call has video and audio

請幫助我調試Chrome瀏覽器的無音頻問題。

任何幫助將不勝感激。

Answer 1

您在星號服務器中啟用了vp8編解碼器，如果沒有，則嘗試從sip.conf中啟用vp8編解碼器。 如果是，則從瀏覽器將控制台日志復制到此處。

謝謝。！！！！
