网页集成软电话

网页集成软电话需要使用https协议，页面与freeswitch平台建立websocket长连接。使用jssip库进行相关开发

• 生成https自签名证书

1. 下载ssl.ca-0.1.tar.gz

wget http://files.freeswitch.org/downloads/ssl.ca-0.1.tar.gz

2. 解压ssl.ca-0.1.tar.gz

tar zxfv ssl.ca-0.1.tar.gz

3. 执行以下命令

[root@localhost ~]# cd ssl.ca-0.1/
[root@localhost ssl.ca-0.1]# perl -i -pe 's/md5/sha1/g' *.sh
[root@localhost ssl.ca-0.1]# perl -i -pe 's/2048/2048/g' *.sh

4. 生成根证书

[root@localhost ssl.ca-0.1]# ./new-root-ca.sh
No Root CA key round. Generating one
Generating RSA private key, 1024 bit long modulus
.....................++++++
...............................................................++++++
e is 65537 (0x10001)
Enter pass phrase for ca.key:  根证书密码
Verifying - Enter pass phrase for ca.key:
Self-sign the root CA...
Enter pass phrase for ca.key:  根证书密码
You are about to be asked to enter information that will be incorporated
into your certificate request.
What you are about to enter is what is called a Distinguished Name or a DN.
There are quite a few fields but you can leave some blank
For some fields there will be a default value,
If you enter '.', the field will be left blank.
-----
Country Name (2 letter code) [MY]:CN  国籍
State or Province Name (full name) [Perak]:bj 省份
Locality Name (eg, city) [Sitiawan]:bj  市
Organization Name (eg, company) [My Directory Sdn Bhd]:qd 公司名称
Organizational Unit Name (eg, section) [Certification Services Division]:ts 组织名称
Common Name (eg, MD Root CA) []:su 常用名
Email Address []:[e-mail]  邮箱地址

• 执行完毕后,会在当前目录生成ca.key和ca.crt两个文件

5. 为服务器生成一个证书

[root@localhost ssl.ca-0.1]# ./new-server-cert.sh  server 
Fill in certificate data
You are about to be asked to enter information that will be incorporated
into your certificate request.
What you are about to enter is what is called a Distinguished Name or a DN.
There are quite a few fields but you can leave some blank
For some fields there will be a default value,
If you enter '.', the field will be left blank.
-----
Country Name (2 letter code) [MY]:CN
State or Province Name (full name) [Perak]:bj
Locality Name (eg, city) [Sitiawan]:bj
Organization Name (eg, company) [My Directory Sdn Bhd]:qd
Organizational Unit Name (eg, section) [Secure Web Server]:ts
Common Name (eg, www.domain.com) []:www.fstest.com 此处须域名
Email Address []:[e-mail]
You may now run ./sign-server-cert.sh to get it signed

• 执行完毕后,生成了server.csr和server.key这两个文件

6. 签署证书使证书生效

[root@localhost ssl.ca-0.1]# ./sign-server-cert.sh server
CA signing: server.csr -> server.crt:
Using configuration from ca.config
Enter pass phrase for ./ca.key:
Check that the request matches the signature
Signature ok
The Subject's Distinguished Name is as follows
countryName           :PRINTABLE:'CN'
stateOrProvinceName   :PRINTABLE:'bj'
localityName          :PRINTABLE:'bj'
organizationName      :PRINTABLE:'qd'
organizationalUnitName:PRINTABLE:'ts'
commonName            :PRINTABLE:'www.fstest.com'
emailAddress          :IA5STRING:'[e-mail]'
Certificate is to be certified until Nov  9 06:26:54 2019 GMT (365 days)
Sign the certificate? [y/n]:y
1 out of 1 certificate requests certified, commit? [y/n]y
Write out database with 1 new entries
Data Base Updated
CA verifying: server.crt <-> CA cert
server.crt: OK

• 出现：/etc/pki/CA/index.txt: No such file or directory执行命令：
  touch /etc/pki/CA/index.txt
• 出现：/etc/pki/CA/serial: No such file or directory执行命令：
  echo 00 > /etc/pki/CA/serial
• 执行完毕后,生成了server.crt文件

配置freeswitch开启wss

1. 生成wss.pem

[root@localhost ssl.ca-0.1]# cat server.crt server.key > wss.pem

2. 替换（备份）freeswitch证书文件

[root@localhost certs]# cd /usr/local/freeswitch/certs/
[root@localhost certs]# ls
dtls-srtp.pem  tls.pem  wss.crt  wss.pem
删除已有的dtls-srtp.pem，FS重启后会自动生成！
[root@localhost certs]# rm -rf dtls-srtp.pem wss.pem 
[root@localhost certs]# cp /usr/local/freeswitch/certs/wss.pem ./
[root@localhost certs]# ls
tls.pem  wss.crt  wss.pem
[root@localhost certs]# freeswitch -stop
Killing: 26732
[root@localhost certs]# freeswitch -nc
29868 Backgrounding.

3. 修改freeswitch配置文件

1. 修改internal.xml

[root@254 ssl.ca-0.1]# vim /usr/local/freeswitch/conf/sip_profiles/internal.xml
设置wss-binding,默认为7443,可修改
<param name="wss-binding" value=":7443"/>

1. 修改vars.xml

[root@254 ssl.ca-0.1]# vim /usr/local/freeswitch/conf/vars.xml
设置以下参数
<X-PRE-PROCESS cmd="set" data="internal_ssl_enable=true"/>
<X-PRE-PROCESS cmd="set" data="external_ssl_enable=true"/>

1. 如果是局域网使用，得做一个 ACL 配置，否则不通

conf/autoload_configs/acl.conf.xml 中，加入下面配置：
<list name="localnet.auto" default="allow">
</list>
然后，conf/sip_profiles/internal.xml 中加入下列配置：
<param name="apply-candidate-acl" value="rfc1918.auto"/>
<param name="apply-candidate-acl" value="localnet.auto"/>

3. 检查是否成功

执行此命令可以看到wss所绑定的端口
[root@254 ssl.ca-0.1]# fs_cli -x 'sofia status profile internal' | grep WSS-BIND-URL
WSS-BIND-URL     	sips:mod_sofia@192.168.0.254:7443;transport=wss

3. 最后再次重启或F6重新加载配置

nginx配置自签名https域名

1. 确定nginx已经安装，且支持https

[root@localhost ~]# nginx  -V
nginx version: nginx/1.9.1
built by gcc 4.8.5 20150623 (Red Hat 4.8.5-44) (GCC) 
built with OpenSSL 1.0.2k-fips  26 Jan 2017
TLS SNI support enabled
configure arguments: --prefix=/data/nginx --with-http_ssl_module

• 一定确保出现：--with-http_ssl_module 否则需要自行安装

2. 配置nginx.conf文件

vim /data/nginx/conf/nginx.conf	
#user  nobody;
worker_processes  1;
events {
    worker_connections  1024;
}
http {
    include       mime.types;
    default_type  application/octet-stream;  
    sendfile        on;
    #tcp_nopush     on;
    #keepalive_timeout  0;
    keepalive_timeout  65;
    #gzip  on;
    # HTTPS server
    server {
        listen    443 ssl;
        server_name  fstest.com  www.fstest.com;
        ssl on;
        ## server.crt 和server.key 是上面生成的证书文件
        ssl_certificate     /root/ssl.ca-0.1/server.crt; 
        ssl_certificate_key  /root/ssl.ca-0.1/server.key;   
    #    ssl_session_cache    shared:SSL:1m;
        ssl_session_timeout  50m;
    #    ssl_ciphers  HIGH:!aNULL:!MD5;
    #    ssl_prefer_server_ciphers  on;

        location / {
 			root /data/demo/;  #前端编译后的静态页面目录 
           }
    }
	server {
    	listen 80;
   	 	server_name fstest.com  www.fstest.com; #多个域名用空格分开
    	#将请求转成https
    	rewrite ^(.*)$ https://$host$1 permanent;
       }
}

页面集成软电话开发

• 使用jssip类库集成。详情参见jssip官方文档和官方demo或者本篇文章使用的demo（推荐）
• 测试通话

1. 修改本机hosts文件，以Mac系统为例：

打开命令行窗口 或者 item
sudo vi /etc/hosts
输入密码
加入：192.168.1.34 www.fstest.com
:wq保存退出

1. 打开浏览器（chorme）地址栏输入：

chrome://flags/#unsafely-treat-insecure-origin-as-secure

如下图设置

1. 重启浏览器后地址栏输入:https://www.fstest.com （结合nginx配置）
   如下图设置

输入账号，密码，先注册，成功后即可拨打或者接听电话！
