本文介绍了Websocket连接失败,并带有星号11的处理方法,对大家解决问题具有一定的参考价值,需要的朋友们下面随着小编来一起学习吧!

问题描述

我正在尝试配置websocket以与星号11一起使用.但是存在一些问题.我遵循的步骤是:在http.conf中启用了以下

I am trying to configure the websocket to work with asterisk 11. But there is some issue.The steps I have followed are:In http.conf enabled the following

enabled=yes
bindaddr=0.0.0.0
bindport=8088

我还为星号配置了DTLS支持.但是当我尝试连接到新的Websocket WebSocket("ws://mySeverIp:8088/ws")时; .引发错误

I have also configured the asterisk with DTLS support.But when I try to connect to the websocket new WebSocket ("ws://mySeverIp:8088/ws"); . It throws an error

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

任何人都可以帮忙.

谢谢

推荐答案

此处是完整的安装指南.如果这可以解决您的问题,请告诉我.Asterisk还提供了有关此事的Wiki帖子

Here is a complete install guide. Please let me know if this solves your problem.Asterisk also provide a 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:

Install 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):

Install UUID Development Library (not required for Asterisk 12) :

cd ~
sudo apt-get install uuid-dev -y (for Debian & ubuntu, libuuid-devel for CentOS)

安装星号11:

cd ~
wget http://downloads.asterisk.org/pub/telephony/asterisk/asterisk-11-current.tar.gz
tar -xzf asterisk-11-current.tar.gz

生成并安装SRTP的DTLS证书:

Generate and install DTLS certificates for SRTP :

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:

To generate a self-signed SSL certificate, use the following command :

### 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.每次输入相同的键,并按Enter键有效.

During this process, you will be asked to choose a key. Type in the same key every time and valid by pressing Enter key.

如果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/

If you will generate you SSL Certificate from a Certification Authority, use the following methods :
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

The certificate path in this example is /etc/asterisk/keys/asterisk.pem

安装星号(是的,您需要使用PJPROJECT和LIBSRTP编译星号):

Install Asterisk (Yes, you need to compile Asterisk with PJPROJECT and LIBSRTP) :

cd ~
cd asterisk*
sudo ./configure --with-pjproject --with-ssl --with-srtp
make menuselect

检查软件包pbx_realtimeres_odbcres_http_websocketres_cryptochan_sip是否已激活.为了在Asterisk中的WS或WSS上使用WebRTC,这是必须具备的.

Check that packages pbx_realtime, res_odbc, res_http_websocket, res_crypto and chan_sip are activated. This is a must have in order to use WebRTC over WS or WSS in Asterisk.

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

激活/etc/asterisk/http.conf中的WebSocket和SecureWebSockets(管理HTTP Apache Asterisk Web实例的文件).如果使用Asterisk Realtime(ODBC),则必须在每个对等方中指定文件(表sippeers中的行dtlscertfiledtlsprivatekey). :

Activate WebSockets ans SecureWebSockets in /etc/asterisk/http.conf (file which manage the HTTP Apache Asterisk Web instance). If you use Asterisk Realtime (ODBC) then you will have to specify the file in each peer (Row dtlscertfile & dtlsprivatekey in table sippeers). :

enabled=yes;
bindport=8088;
tlscertfile=/etc/asterisk/keys/asterisk.pem
tlsprivatekey=/etc/asterisk/keys/asterisk.pem

确保文件夹上的权限良好:(由运行Asterisk Service的用户替换AsteriskUser)

Ensure that rights on folders are good : (replace AsteriskUser by the user running Asterisk Service)

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(重复以创建另一个用户):

Create your WebRTC peers in sip.conf (duplicate to make another user) :

[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:

Edit extensions.conf to allow each peer to call :

[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

启动星号服务:

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

Restart (or start) the service : sudo service asterisk restart

从另一台计算机上测试WebSockets:使用sudo apt-get install wscat –y

Test WebSockets from another machine : Install WSCAT with 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Java客户端(例如JsSIP,sipML5,WebRTComm,...)通过WebSocket测试您的SIP.

Test your SIP over WebSocket using a Javascript client such as JsSIP, sipML5, WebRTComm, ...

使用sudo asterisk -vvvvvv -g -dddddd -r访问SIP控制台以进行调试和跟踪.

Access the SIP console using sudo asterisk -vvvvvv -g -dddddd -r to debug and trace.

要对Asterisk 12进行同样的操作,只需在Asterisk安装中将Asterisk-11替换为Asterisk-12.

To do the same with Asterisk 12, simply replace Asterisk-11 by Asterisk-12 in Asterisk install.

在这里您将找到使用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:

Here you'll find complete conf files for Asterisk 12 using Realtime, WS, WSS (ommitting ODBC conf). I post it because you may find usefull to check if some parameter is missing in your install :
