通过Ubuntu 12.04 x64 部署opensips、rtpproxy、mediaproxy，实现了sip服务、媒体转发等服务。通过配置与测试，还支持ICE方式建立点对点的音视频会话。花了些时间折腾，大家如有问题请留言沟通。
软件版本：
opensips: opensips_1_10 （下载编译再安装）
rtpproxy: Basic version: 20040107 （直接安装）
mediaproxy: mediaproxy-2.5.2 （下载编译再安装）
客户端: Microsip 测试
安装与配置的步骤：
一、opensips
编译opensips 1.10
make menuconfig
如下配置参数：
1 Configure Compile Options -> Configure Excluded Modules :
[*] db_mysql
[*] dialplan
2 Configure Compile Options -> Configure Install Prefix ：/usr/local/sbin/
3 Compile And Install OpenSIPS，直此安装完成。（如果少了些什么库，请apt-get install xxx)
生成脚本
安装位置在/usr/local/sbin。其中，sbin为程序目录，etc为配置参数所在目录，还有lib64和share两个目录。
利用 /usr/local/sbin/sbin/osipsconfig 生成配置文件,具体操作
1 Generate OpenSIPS Script ->Residential Script -> Configure Residential Script :
[*] ENABLE_TCP
[*] USE_AUTH
[*] USE_DBACC
[*] USE_DBUSRLOC
[*] USE_NAT
2 Save Residential Script
3 Generate Residential Script：生成配置文件位于/usr/local/sbin//etc/opensips/opensips_residential_xxx.cfg
编辑参数
进入/usr/local/sbin/etc/opensips，覆盖旧的配置文件: cp opensips_residential_xxx.cfg opensips.cfg
编辑opensips.cf文件，修改如下(注意红色部分）：
