第二部分：MediaProxy的安装与配置
安装依赖包
yum -y groupinstall “Development Tools” yum -y install gcc gcc-c++ iptables-devel libnfnetlink-devel libnetfilter_conntrack-devel libgcrypt-devel libgpg-error-devel gnutls python-devel python-zope-interface
2.安装python-cjson-1.0.5.tar.gz
wget https://pypi.python.org/packages/source/p/python-cjson/python-cjson-1.0.5.tar.gz tar zxf python-cjson-1.0.5.tar.gz cd python-cjson-1.0.5 ./setup.py build ./setup.py install cd
3.安装python-application-1.3.0.tar.gz
wget https://pypi.python.org/packages/source/p/python-application/python-application-1.3.0.tar.gz tar zxf python-application-1.3.0.tar.gz cd python-application-1.3.0 ./setup.py build ./setup.py install cd
4.安装python-gnutls-1.2.4.tar.gz
wget https://pypi.python.org/packages/source/p/python-gnutls/python-gnutls-1.2.4.tar.gz tar zxf python-gnutls-1.2.4.tar.gz cd python-gnutls-1.2.4 ./setup.py build ./setup.py install cd
5.安装Twisted-11.0.0.tar.bz2
wget http://twistedmatrix.com/Releases/Twisted/11.0/Twisted-11.0.0.tar.bz2 tar jxf Twisted-11.0.0.tar.bz2 cd Twisted-11.0.0 ./setup.py build ./setup.py install cd
6.安装mediaproxy-2.5.2.tar.gz
wget http://download.ag-projects.com/MediaProxy/old/mediaproxy-2.5.2.tar.gz tar zxf mediaproxy-2.5.2.tar.gz cd mediaproxy-2.5.2 ./setup.py build ./setup.py install cd
7.配置mediaproxy
mkdir /etc/mediaproxy mkdir -p /var/run/mediaproxy mkdir -p /var/run/opensips cp -rf /root/mediaproxy-2.5.2/tls/ /etc/mediaproxy/ #生成mediaproxy的配置文件 cat << EOF >/etc/mediaproxy/config.ini [Relay] dispatchers = 192.168.88.10 passport = None relay_ip = 192.168.88.10 port_range = 50000:60000 [Dispatcher] socket_path = dispatcher.sock listen = 192.168.88.10 listen_management = 192.168.88.10 passport = None management_passport = None [TLS] [Database] [Radius] [OpenSIPS] socket_path = /var/run/opensips/socket max_connections = 10 EOF #将以上IP改为本机的IP
8.配置Linux内核设置转发
sed -i ‘s#net.ipv4.ip_forward = 0#net.ipv4.ip_forward = 1#g‘ /etc/sysctl.conf sysctl -p
9.启动mediaproxy及中继
media-dispatcher media-relay
#在启动的时候一定要观察/var/log/message
10.在opensips配置文件中增加
#add for mediaproxy#######################################
loadmodule "mediaproxy.so"
modparam("mediaproxy", "disable", 0)
modparam("mediaproxy", "mediaproxy_socket", "/var/run/mediaproxy/dispatcher.sock")
modparam("mediaproxy", "mediaproxy_timeout", 1000)
modparam("mediaproxy", "signaling_ip_avp", "$avp(nat_ip)")
modparam("mediaproxy", "media_relay_avp", "$avp(media_relay)")
modparam("mediaproxy", "ice_candidate", "low-priority")
最后opensips.cfg的配置文件就是

#
# OpenSIPS residential configuration script

#
# This script was generated via "make menuconfig", from

}最后，如果要使用ICE，必须要有客户端支持，也还要有STUN服务器(外部有免费的STUN服务器)。
如在LINPHONE的设置中，“设置”--“NetWork”--“STUN SERVER”，输入STUN服务器地址。然后开启“Enable ICE”
这个时候拨打电话如果是P2P的话就会出现HOST CONNECTION
如果是无法点对点的话，ICE的状态就是RELAY CONNECTION.
