我正在尝试配置websocket以使用星号11.但是存在一些问题。 我遵循的步骤是： 在http.conf中启用了以下
enabled=yes
bindaddr=0.0.0.0
bindport=8088
我还配置了支持DTLS的星号。 但是当我尝试连接到websocket新的WebSocket时（＆＃34; ws：// mySeverIp：8088 / ws＆＃34;）; 。它会抛出错误
WebSocket connection failed: Error during WebSocket handshake: Unexpected response code: 400
任何人都请帮忙。

这是完整的安装指南。如果这可以解决您的问题，请告诉我。 星号也提供wiki post on the matter
安装SRTP：
cd ~
git clone https://github.com/cisco/libsrtp.git
cd libsrtp/
autoconf
./configure CFLAGS=-fPIC --prefix=/usr
make
make runtest
sudo make install
安装PJPROJECT：
cd ~
git clone https://github.com/asterisk/pjproject pjproject
cd pjproject/
./configure --prefix=/usr --enable-shared --disable-sound --disable-resample --disable-video --disable-opencore-amr --with-external-srtp
make
sudo make install
安装UUID开发库（Asterisk 12不需要）：
cd ~
sudo apt-get install uuid-dev -y (for Debian & ubuntu, libuuid-devel for CentOS)
安装Asterisk 11：
cd ~
wget http://downloads.asterisk.org/pub/telephony/asterisk/asterisk-11-current.tar.gz
tar -xzf asterisk-11-current.tar.gz
为SRTP生成并安装DTLS证书：
cd asterisk*/contrib/scripts
sudo mkdir /etc/asterisk/
sudo mkdir /etc/asterisk/keys/
要生成自签名SSL证书，请使用以下命令：
### Replace 10.x.x.x by the IP adress of your server. 10.x.x.x is intern, use a public IP if your Asterisk will be exposed over Internet.
sudo ./ast_tls_cert -C 10.x.x.x -O "Your Company" -d /etc/asterisk/keys
在此过程中，系统会要求您选择一个密钥。每次输入相同的密钥，按Enter键即可生效。
如果您要从证书颁发机构生成SSL证书，请使用以下方法：
http://codeghar.wordpress.com/2013/04/16/generate-certificate-signing-request-on-linux/
http://codeghar.wordpress.com/2013/04/16/use-private-certificate-authority-to-sign-certificate-signing-request-on-linux/
此示例中的证书路径为/etc/asterisk/keys/asterisk.pem
安装Asterisk（是的，您需要使用PJPROJECT和LIBSRTP编译Asterisk）：
cd ~
cd asterisk*
sudo ./configure --with-pjproject --with-ssl --with-srtp
make menuselect
检查已激活软件包pbx_realtime，res_odbc，res_http_websocket，res_crypto和chan_sip。为了在Asterisk中使用WebRTC而不是WS或WSS，这是必须的。
make
sudo make install
sudo make config
## Recommended demo conf files with :
sudo make samples
cd ~
在/etc/asterisk/http.conf（管理HTTP Apache Asterisk Web实例的文件）中激活WebSockets和SecureWebSockets。如果使用Asterisk Realtime（ODBC），则必须在表dtlscertfile中的每个对等方（行dtlsprivatekey＆amp; sippeers）中指定文件。 ：
enabled=yes;
bindport=8088;
tlscertfile=/etc/asterisk/keys/asterisk.pem
tlsprivatekey=/etc/asterisk/keys/asterisk.pem
确保文件夹的权限良好:(由运行Asterisk服务的用户替换AsteriskUser）
sudo chown AsteriskUser. /var/run/asterisk
sudo chown -R AsteriskUser. /etc/asterisk
sudo chown -R AsteriskUser. /var/{lib,log,spool}/asterisk
sudo chown -R AsteriskUser. /usr/lib/asterisk
在sip.conf中创建WebRTC对等体（复制以生成其他用户）：
[1060] ; This will be WebRTC client
type=friend ;
username=1060 ; The Auth user for SIP.js
host=dynamic ; Allows any host to register
secret=password ; The SIP Password for SIP.js
encryption=yes ; Tell Asterisk to use encryption for this peer
avpf=yes ; Tell Asterisk to use AVPF for this peer
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,wss ; 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
dtlscertfile=/etc/asterisk/keys/asterisk.pem ; Tell Asterisk where your DTLS cert file is
dtlsprivatekey=/etc/asterisk/keys/asterisk.pem ; Tell Asterisk where your DTLS private key is
dtlssetup=actpass ; Tell Asterisk to use actpass SDP parameter when setting up DTLS
[1061] ; This will be the legacy SIP client
type=friend;
username=1061;
host=dynamic;
secret=password;
context=default;
编辑extensions.conf以允许每个对等方呼叫：
[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
启动Asterisk服务：
sudo service asterisk start
打开所需的端口：
[Ubuntu] :
sudo ufw allow 5060 (or whatever port you have choosen in sip.conf `udpbindaddr=10.x.x.x:5060; tcpbindaddr=10.x.x.x:5060;tlsbindaddr=10.x.x.x:5061`)
sudo ufw allow 5061
sudo ufw allow 8088 (or whatever port you have choosen in http.conf : `bindport=8088`)
sudo ufw allow 8089 (or whatever port you have choosen in http.conf : `tlsbindaddr=10.x.x.x:8089`)
sudo ufw allow 10000:20000/udp (or whatever range you have choosen in rtp.conf : `rtpstart=10000; rtpend=20000`)
[or if you are on Debian] :
sudo iptables -A INPUT -p tcp --dport 5060 -j ACCEPT
sudo iptables -A INPUT -p tcp --dport 5061 -j ACCEPT
sudo iptables -A INPUT -p tcp --dport 8088 -j ACCEPT
sudo iptables -A INPUT -p tcp --dport 8089 -j ACCEPT
sudo iptables -A INPUT -p tcp --match multiport --dports 10000:20000 -j ACCEPT
重新启动（或启动）服务：sudo service asterisk restart
从另一台计算机测试WebSockets：使用sudo apt-get install wscat –y
## If error "connect ECONNREFUSED" it's not OK.
## If Echo service returns your messages, it's OK.
wscat -s echo -c ws://10.x.x.x:8088/ws
## The same command with WSS should work if you've installed WSS.
使用Js客户端（如JsSIP，sipML5，WebRTComm，...）测试您的SIP over WebSocket
使用sudo asterisk -vvvvvv -g -dddddd -r访问SIP控制台以进行调试和跟踪。
要对Asterisk 12执行相同操作，只需在Asterisk安装中用Asterisk-12替换Asterisk-11。
在这里，您将使用Realtime，WS，WSS（省略ODBC conf）找到Asterisk 12的完整conf文件。我发布它是因为您可能会发现有用来检查安装中是否缺少某些参数：

; defaults to "asterisk". If you set a system name in
; asterisk.conf, it defaults to that system name
; Realms MUST be globally unique according to RFC 3261
; Set this to your host name or domain name
udpbindaddr=10.x.x.x ; IP address to bind UDP listen socket to (0.0.0.0 binds to all)
; Optionally add a port number, 192.168.1.1:5062 (default is port 5060)
videosupport=yes ; Turn on support for SIP video. You need to turn this
; on in this section to get any video support at all.
; You can turn it off on a per peer basis if the general
; video support is enabled, but you can't enable it for
; one peer only without enabling in the general section.
; If you set videosupport to "always", then RTP ports will
; always be set up for video, even on clients that don't
; support it. This assists callfile-derived calls and
; certain transferred calls to use always use video when
; available. [yes|NO|always]
rtsavepath=yes ; If using dynamic realtime, store the path headers
send_diversion=no ; Default "yes" ; Asterisk normally sends Diversion headers with certain SIP
; invites to relay data about forwarded calls. If this option
; is disabled, Asterisk won't send Diversion headers unless
; they are added manually.
rtpkeepalive=2 ; Send keepalives in the RTP stream to keep NAT open (default is off - zero)(secs)

; as-needed basis? (yes|no)
rtsavesysname=yes ; Save systemname in realtime database at registration
; Default= no
rtupdate=yes ; Send registry updates to database using realtime? (yes|no)
; If set to yes, when a SIP UA registers successfully, the ip address,
; the origination port, the registration period, and the username of
; the UA will be set to database via realtime.
; If not present, defaults to 'yes'. Note: realtime peers will
; probably not function across reloads in the way that you expect, if
; you turn this option off.
rtautoclear=yes ; Auto-Expire friends created on the fly on the same schedule
; as if it had just registered? (yes|no|<seconds>)
; If set to yes, when the registration expires, the friend will
