asterisk配置实现sip服务器，进行sip视频通话




配置asterisk
1.下载asterisk
sudo apt-get install asterisk

2.配置sip.conf文件
sip.conf文件的目录默认在/etc/asterisk/下，修改之前最好备份一下，在/etc/目录下执行：
sudo cp ./asterisk/ ./asteriskbak -rf

在sip.conf文件中修改：
[general]
context=default
; Note that the TCP and TLS support for chan_sip is currently considered
; experimental. Since it is new, all of the related configuration options are
; subject to change in any release. If they are changed, the changes will
; be reflected in this sample configuration file, as well as in the UPGRADE.txt file.
;
tcpenable=yes ; Enable server for incoming TCP connections (default is no)
;compactheaders = yes ; send compact sip headers.
;
;videosupport=yes ; Turn on support for SIP video. You need to turn this

文件最后添加用户：
[505]
videosupport=always
type = friend
username=505
secret = 505
host = dynamic
canreinvite = no
dtmfmode = rfc2833
mailbox = mailbox
transport = udp
nat=yes
videosupport=always
maxcallbitrate=384
canreinvite=no
disallow=all
allow = ulaw
allow=alaw
allow=h263
allow=h264
context=default
[506]
videosupport=always
type = friend
username=506
secret = 506
host = dynamic
canreinvite = no
dtmfmode = rfc2833
mailbox = mailbox
transport = udp
nat=yes
videosupport=always
maxcallbitrate=384
canreinvite=no
disallow=all
allow = ulaw
allow=alaw
allow=h263
allow=h264
context=default

中间省略了无需修改的内容。
2.配置extensions.conf文件
在extensions.conf文件中修改为：
[default]
;
; By default we include the demo. In a production system, you
; probably don't want to have the demo there.
;
include => demo
exten => 505,1,Dial(SIP/505)
exten => 506,1,Dial(SIP/506)

3.启动asterisk
执行以下命令：
sudo asterisk

配置sip客户端
1.下载MicroSIP客户端
MicroSIP为windows运行程序
https://www.microsip.org/downloads


2. 配置MicroSIP客户端
点击图示，选择添加账号
之后的页面如图：
配置完之后如图，显示在线状态
域名和sip服务器一样都是，我的服务器IP为192.168.1.9，sip服务器端口一般都为5060 密码也是505，就是sip.conf中配置用户名密码。 相同的配置，在找局域网中的其他电脑将MicroSIP配置成506的账号即可 输入506点击红色方框进行视频通话
