SIP Express Router (SER) 安装备忘录一（原创）

老早以前玩过的一个Sip Server，今天翻出来，备忘～
http://www.iptel.org/ser

安装平台是Opensuse10.2，所以呢，为了省事，有意找了rpm包来装：
ser-0.9.6-6.fc5.i386.rpm
http://rpm.pbone.net/index.php3/stat/3/srodzaj/1/search/ser
ser-mysql-0.9.6-6.fc5.i386.rpm
http://rpm.pbone.net/index.php3?stat=3&search=ser-mysql&srodzaj=3

root:~ #rpm -ivh ......

和大多数linux程序一样，配置都源于.cfg文件，所以装完了rpm包，就直接找ser.cfg，找不到的话就找程序根目录：

root:~ # locate ser.cfg
root:~ # whereis ser
ser: /usr/sbin/ser /etc/ser /usr/lib/ser /usr/share/man/man8/ser.8.gz

一看就知道应该在/etc/ser/下，简单编辑一下吧：

root:~ #vi /etc/ser/ser.cfg

#
# $Id: ser.cfg,v 1.25.2.1 2005/02/18 14:30:44 andrei Exp $
#
# simple quick-start config script
#

# ----------- global configuration parameters ------------------------

debug=3 # debug level (cmd line: -dddddddddd)
fork=no
log_stderror=yes # (cmd line: -E)

/* Uncomment these lines to enter debugging mode
fork=no
log_stderror=yes
*/

listen=10.74.121.71


check_via=no # (cmd. line: -v)
dns=no # (cmd. line: -r)
rev_dns=no # (cmd. line: -R)
#port=5060
#children=4
fifo="/tmp/ser_fifo"

# ------------------ module loading ----------------------------------

# Uncomment this if you want to use SQL database
#loadmodule "/usr/lib/ser/modules/mysql.so"

loadmodule "/usr/lib/ser/modules/sl.so"
loadmodule "/usr/lib/ser/modules/tm.so"
loadmodule "/usr/lib/ser/modules/rr.so"
loadmodule "/usr/lib/ser/modules/maxfwd.so"
loadmodule "/usr/lib/ser/modules/usrloc.so"
loadmodule "/usr/lib/ser/modules/registrar.so"
loadmodule "/usr/lib/ser/modules/textops.so"

# Uncomment this if you want digest authentication
# mysql.so must be loaded !
#loadmodule "/usr/lib/ser/modules/auth.so"
#loadmodule "/usr/lib/ser/modules/auth_db.so"

# ----------------- setting module-specific parameters ---------------

# -- usrloc params --

modparam("usrloc", "db_mode", 0)

# Uncomment this if you want to use SQL database
# for persistent storage and comment the previous line
#modparam("usrloc", "db_mode", 2)

# -- auth params --
# Uncomment if you are using auth module
#
#modparam("auth_db", "calculate_ha1", yes)
#
# If you set "calculate_ha1" parameter to yes (which true in this config),
# uncomment also the following parameter)
#
#modparam("auth_db", "password_column", "password")

# -- rr params --
# add value to ;lr param to make some broken UAs happy
modparam("rr", "enable_full_lr", 1)


# ------------------------- request routing logic -------------------

# main routing logic

route{

# initial sanity checks -- messages with
# max_forwards==0, or excessively long requests
if (!mf_process_maxfwd_header("10")) {
sl_send_reply("483","Too Many Hops");
break;
};
if (msg:len >= 2048 ) {
sl_send_reply("513", "Message too big");
break;
};


# we record-route all messages -- to make sure that
# subsequent messages will go through our proxy; that's
# particularly good if upstream and downstream entities
# use different transport protocol
if (!method=="REGISTER") record_route();

# subsequent messages withing a dialog should take the
# path determined by record-routing
if (loose_route()) {
# mark routing logic in request
append_hf("P-hint: rr-enforced\r\n");
route(1);
break;
};

if (!uri==myself) {
# mark routing logic in request
append_hf("P-hint: outbound\r\n");
route(1);
break;
};
# if the request is for other domain use UsrLoc
# (in case, it does not work, use the following command
# with proper names and addresses in it)
if (uri==myself) {

if (method=="REGISTER") {

# Uncomment this if you want to use digest authentication
# if (!www_authorize("iptel.org", "subscriber")) {
# www_challenge("iptel.org", "0");
# break;
# };

save("location");
break;
};

lookup("aliases");
if (!uri==myself) {
append_hf("P-hint: outbound alias\r\n");
route(1);
break;
};

# native SIP destinations are handled using our USRLOC DB
if (!lookup("location")) {
sl_send_reply("404", "Not Found");
break;
};
};
append_hf("P-hint: usrloc applied\r\n");
route(1);
}

route[1]
{
# send it out now; use stateful forwarding as it works reliably
# even for UDP2TCP
if (!t_relay()) {
sl_reply_error();
};
}

几乎默认即可，主要是记住将 listen=x.x.x.x 打开

好了，程序可以跑起来了：

找俩电话，注册上去打打看吧，没认证的，同时你可以用monitor来监控一下：
