服务器评测通过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）：

modparam(“mediaproxy”, “media_relay_avp”, “$avp(media_relay)”)
modparam(“mediaproxy”, “ice_candidate”, “low-priority”)
配置opensipsctlrc，修改内容如下（注意红色部分）：
## your SIP domain
SIP_DOMAIN=x.x.x.x
## chrooted directory
# $CHROOT_DIR=”/path/to/chrooted/directory”
## database type: MYSQL, PGSQL, Oracle, DB_BERKELEY, or DBTEXT,
## by default none is loaded
# If you want to setup a database with opensipsdbctl, you must at least specify
# this parameter.
DBENGINE=MYSQL
## database host
DBHOST=localhost
## database name (for ORACLE this is TNS name)
DBNAME=opensips
# database path used by dbtext or db_berkeley
# DB_PATH=”/usr/local/etc/opensips/dbtext”
## database read/write user
DBRWUSER=opensips
## password for database read/write user
DBRWPW=”opensipsrw”
## database super user (for ORACLE this is ‘scheme-creator’ user)
DBROOTUSER=”root”
# user name column
USERCOL=”username”
- 建立数据库
进入/usr/local/sbin/sbin ,
./opensipsdbctl create
- 建立sip帐户
./opensipsctl add test test
- 开启sip服务(注：一般在开启rtpproxy, mediaproxy服务后，最后再开启sip服务）
./opensipsctl start
二、安装并配置rtpproxy
参考 http://www.linuxidc.com/Linux/2014-01/95845.htm
三、编译并安装mediaproxy: （注：需要安装Python库）
./setup.py build
./setup.py setup
我遇到的问题： 运行media-relay –no-fork, 出现media-relay Segmentation fault， 导致程序崩溃。
需要下载一个libgcrypt11_1.5.0-3Ubuntu0.1+agp_amd64.deb 安装一下，问题解决。
开启服务：
service mediaproxy-relay start
service mediaproxy-dispatcher start
