Websocket 连接失败并显示 Asterisk 11

我正在尝试配置 websocket 以使用 asterisk 11。但是有一些问题。我遵循的步骤是:在 http.conf 中启用以下内容

enabled=yes
bindaddr=0.0.0.0
bindport=8088

我还为 Asterisk 配置了 DTLS 支持。但是当我尝试连接到 websocket new WebSocket ("ws://mySeverIp:8088/ws") 时; .它抛出一个错误

WebSocket connection failed: Error during WebSocket handshake: Unexpected response code: 400  

任何人请帮助。

谢谢

最佳答案

这是完整的安装指南。如果这能解决您的问题,请告诉我。Asterisk 还提供了一个 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 key 。每次输入相同的键并按 Enter 键有效。

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/

本例证书路径为/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

检查包 pbx_realtimeres_odbcres_http_websocketres_cryptochan_sip被激活。这是在 Asterisk 中使用 WebRTC over WS 或 WSS 的必备条件。

make
sudo make install
sudo make config
## Recommended demo conf files with :
sudo make samples
cd ~

/etc/asterisk/http.conf(管理 HTTP Apache Asterisk Web 实例的文件)中激活 WebSockets 和 SecureWebSockets。如果您使用 Asterisk Realtime (ODBC),那么您必须在每个对等节点中指定文件(sippeers 表中的行 dtlscertfile & dtlsprivatekey)。 :

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:(将 AsteriskUser 替换为运行 Asterisk 服务的用户)

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 中创建您的 WebRTC 对等点(复制以创建另一个用户):

[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 以允许每个对等点调用:

[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

从另一台机器测试 WebSockets:使用 sudo apt-get install wscat –y 安装 WSCAT

## 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 JsSIP、sipML5、WebRTComm 等 Javascript 客户端通过 WebSocket 测试您的 SIP

使用 sudo asterisk -vvvvvv -g -dddddd -r 访问 SIP 控制台进行调试和跟踪。

要对 Asterisk 12 做同样的事情,只需在 Asterisk 安装中用 Asterisk-12 替换 Asterisk-11。

在这里您可以找到使用 Realtime、WS、WSS(省略 ODBC conf)的 Asterisk 12 的完整 conf 文件。我发布它是因为您可能会发现检查安装中是否缺少某些参数很有用:

; 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

; they are added manually.

; 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

; instead of the registration interval.

如果您使用实时,请插入以下通用拨号方案:

INSERT INTO `extensions`    (   `context`,  `exten`,    `priority`,     `app`,  `appdata`   ) VALUES    (   'default',  '_X.',  1,  'Dial',     'SIP/${EXTEN}'  );
