1. Supported Architectures and Requirements

Supported architectures: Linux/i386, Linux/armv4l, FreeBSD/i386, OpenBSD/i386 Solaris/sparc64, NetBSD/sparc64 (for other architectures the Makefiles might need to be edited) There are various configuration options defined in the Makefile.

Requirements:

- gcc or icc : gcc >= 2.9x; 3.[12] recommended (it will work with older version but it might require some options tweaking for best performance)

- bison or yacc (Berkley yacc)

- flex

- GNU make (on Linux this is the standard "make", on FreeBSD and Solaris is called "gmake") version >= 3.79. - sed and tr (used in the makefiles)

- GNU tar ("gtar" on Solaris) and gzip if you want "make tar" to work

- GNU install or BSD install (on Solaris "ginstall") if you want "make install", "make bin", "make sunpkg" to work

- openssl if you want to compile the TLS support

- libmysqlclient & libz (zlib) -libs and devel headers- if you want mysql DB support (the mysql module)

- libpq / postgresql -libs and devel headers- if you want postgres DB support (the postgres module)

- unixodbc -libs and devel headers- if you want unixodbc DB support (the unixodbc module)

- libexpat if you want the jabber gateway support (the jabber module)

- libxml2 if you want to use the cpl-c (Call Processing Language) and PA (Presence Agent) modules

- libradius-ng -libs and devel headers- if you want to use functionalities with radius support - authentication, accounting, group support, etc

OS Notes:

- FreeBSD/OpenBSD/NetBSD: make sure gmake, bison or yacc & flex are installed

- Solaris: as above; you can use Solaris's yacc instead of bison. You might need also gtar and ginstall.

 

2. Howto Build KAMAILIO (OPENSER) From Source Distribution

(NOTE: if make doesn't work try gmake instead)

Compile with default options (TLS support is by default configured):

make #builds only kamailio (openser) core, equivalent to

make kamailio

make modules

 

Other options:

Build everything
make all

Compile debug mode version
make mode=debug all

Compile only the textops module
make modules=modules/textops modules

Compile all the "default" modules except textops and mysql
make skip_modules="textops mysql" modules

Compile all default modules and include uri_radius (not compiled by default)
make include_modules="uri_radius" modules

Compile all the modules from the modules subdirectory (even the one excluded by default)
make exclude_modules="" modules

Compile all the modules from the modules subdirectory excluding exec
make exclude_modules=exec modules or make exclude_modules="" skip_modules=exec modules

Compile with gcc-3.2 instead of gcc
make CC=gcc-3.2 all
or
CC=gcc-3.2 make all

 

Make targets:

Clean:

make clean (clean the modules too)
make proper (clean also the dependencies)
make distclean (the same as proper)
make mantainer-clean (clean everything, including auto generated files, tags, *.dbg a.s.o)

 

Compile:

make proper
make (or gmake on non-Linux systems)
make modules
make modules exclude_modules="CVS exec" etc.

 

Others:

Make tags:
make TAGS

Create a tar.gz with the sources (in ../):
make tar

Create a tar.gz with the binary distribution (in ../):
make bin

Create a gzipped solaris package (in ../):
make sunpkg Create debian packages (in ../):
make deb or dpkg-buildpackage

 

Install: make prefix=/usr/local install

Note: If you use prefix parameter in make install then you also need to use this parameter in previous make commands, i.e. make, make modules, or make all. If you fail to do this then KAMAILIO (OpenSER) will look for the default configuration file in a wrong directory, because the directory of the default configuration file is hard coded into KAMAILIO (OpenSER) during compile time.

When you use a different prefix parameter when installing then the directory hard coded in kamailio (openser) and the directory in which the file will be installed by make install will not match. (You can specify exact location of the configuration file using -f parameter of openser). For example, if you do the following: make all make prefix=/ install Then the installation will put the default configuration file into /etc/kamailio/kamailio.cfg (because prefix is /), but kamailio (openser) will look for the file in /usr/local/etc/kamailio/kamailio.cfg (because there was no prefix parameter in make all and /usr/local is the default value of prefix).

Workaround is trivial, use the same parameters in all make commands: make prefix=/ all make prefix=/ install That applies to other make parameters as well (for example parameters "modules" or "excluded_modules").

3. Quick-Start Installation Guide

A) Getting Help

This guide gives you instructions on how to set up the KAMAILIO (OpenSER) on your box quickly. In case the default configuration does not fly, check documentation at kamailio (openser) site http://www.kamailio.org/ to learn how to configure KAMAILIO (OpenSER) for your site.

If the documentation does not resolve your problem you may try contacting our user forum by E-mail at -- that is the mailing list of kamailio (openser) community. To participate in the mailing list, subscribe at the following web address: http://www.kamailio.org/cgi-bin/mailman/listinfo/users

B) Disclaimers

Note well the default "quick-start" configuration is very simple in order to be easily installable. It provides minimum features. Particularly, authentication is by default disabled, which means anyone can register using any name with the server. (This is on purpose to avoid installation dependencies on MySQL which is needed for storing user credentials.)

C) Quick Start

The following step-by step guide gives you instructions how to install the sql-free distribution of openser. If you need persistence and authentication, then you have to install additional MySql support -- proceed to section D) after you are finished with C).

1) Download an RPM or debian package from our site http://kamailio.org/pub/kamailio/latest/packages/ If you don't use an rpm or debian based distribution, see if corresponding packages are available or try our tar.gz'ed binaries. If you use Gentoo Linux you do not have to download a package.

For debian, APT repositories are available for all versions at:

deb http://www.kamailio.org/debian etch main

deb http://www.kamailio.org/debian sarge main

deb http://www.kamailio.org/debian sid main


2) install the package

RPM: rpm -i

debian: dpkg -i or if APT repository is used: apt-get install

gentoo: emerge kamailio (or if use only stable packets: ACCEPT_KEYWORDS="~x86" emerge kamailio)

tar.gz: cd /; tar zxvf _os_arch.tar.gz (it will install in /usr/local/, and the configuration file in /usr/local/etc/kamailio/kamailio.cfg)

Solaris: gunzip .gz ; pkgadd -d

*BSD: pkg_add package_name

 

3) start the server

RPM + gentoo: /etc/init.d/kamailio start

debian: kamailio (openser) is started automatically after the install (in case something fails you can start it with /etc/init.d/kamailio start)

tar.gz: the tar.gz does not include an init.d script, you'll have to create one of your own or adapt one from the source distribution (debian/init.d, rpm/kamailio.init.*, gentoo/kamailio.init) You can start kamailio (openser) directly with /usr/local/sbin/kamailio.

Solaris: see tar.gz.

 

4) optionally, watch server's health using the kamctl utility - to do so, first set the environment variable SIP_DOMAIN to your domain name, e.g., in Bourne shell, call export SIP_DOMAIN="myserver.foobar.com" - if you are using other than 'localhost' mysql server for maintaining subscriber database, change the variable 'SQL_HOST' to the proper host name in the kamctl script - run the kamctl utility /usr/sbin/kamctl moni or /usr/local/sbin/kamctl moni (if you installed from a tar.gz or solaris package) - you can create a resource file for kamctl, name it .kamctlrc and place it in your home directory. You can set there the values for kamctl variables (e.g., SIP_DOMAIN, SQL_HOST, SQL_USER, SQL_DB ...)

 

5) Register with the server using your favourite SIP User Agent. For example, users of Windows Messenger need to set in Tools->Options->Accounts the following values:

Sign-in Name:

Advanced->Configure Settings (on)

Advanced->Server: Connect Using: UDP


D) KAMAILIO (OpenSER) with Persistent Data Storage

The default configuration is very simple and features many simplifications. In particular, it does not authenticate users and loses User Location database on reboot. To provide persistence, keep user credentials and remember users' locations across reboots, openser can be configured to use MySQL. Before you proceed, you need to make sure MySQL is installed on your box.

1) Download the package containing mysql support for KAMAILIO (OpenSER) from: http://www.kamailio.org/pub/kamailio/ (rpm and deb provided, most of the binary tar.gz distributions and the solaris package include it; if it is not present you'll have to rebuild from the source). For gentoo please include 'mysql' to your USE variable in /etc/make.conf or give it as variable to the emerge command.

2) install the package RPM based: rpm -i DEB based: dpkg -i or if APT repository is used apt-get install Gentoo Linux: emerge kamailio (if do not want to put 'mysql' into your USE variable you can type: USE="mysql" emerge kamailio)

3) create SQL tables If you use MySQL support, use kamdbctl. For Postgres use kamdbctl but change DBENGINE in kamctlrc. - if you have a previously installed KAMAILIO (OpenSER) on your system, use /usr/sbin/kamdbctl reinstall to convert your KAMAILIO (OpenSER) database into new structures - otherwise, if this is your very first installation, use /usr/sbin/kamdbctl create to create OpenSER database structures (you will be prompted for password of MySql "root" user)

4) configure kamailio (openser) to use SQL uncomment all lines in configuration file kamailio.cfg which are related to authentication:

- loadmodule "/usr/lib/kamailio/modules/mysql.so"

- loadmodule "/usr/lib/kamailio/modules/auth.so"

- loadmodule "/usr/lib/kamailio/modules/auth_db.so"

- modparam("usrloc", "db_mode", 2)

- modparam("auth", "calculate_ha1", yes)

- modparam("auth_db", "password_column", "password")

- if (!www_authorize("sip.org", "subscriber")) {

www_challenge("sip.org", "0");

break;

};

5) be sure to replace realm, the first parameter in www_* actions, with name of your server; some broken UAC implementations don't authenticate otherwise; the authentication command in your configuration script should look then like this:

if (!www_authorize("myserver.foobar.com", "subscriber")) {

www_challenge("myserver.foobar.com", "0");

break;

}

6) restart the server /etc/init.d/kamailio restart

7) you can now start managing the server using the kamctl utility; you need to first set the environment variable SIP_DOMAIN to your local SIP realm, e.g.,

export SIP_DOMAIN="myserver.foobar.com"

or you can configure via the resource file for kamctlrc. The default file is installed in the etc/ directory of your installation (along with the KAMAILIO(OpenSER) config file). For per user configuration, create .kamctlrc in your home directory.

You can set there the values for kamctl variables like:

SIP_DOMAIN - your SIP domain

DBENGINE - database type: MYSQL or PGSQL, by defaulte none is loaded

DBHOST - database host DBNAME - database name

DBRWUSER - database read/write user

DBROUSER - database read only user

DBROPW - password for database read only user

DBROOTUSER - database super user

ALIASES_TYPE - type of aliases used: DB - database aliases UL - usrloc aliases default none

CTLENGINE - control engine: FIFO or UNIXSOCK

OSER_FIFO - path to FIFO file

VERBOSE - verbose - debug purposes - default '0'

a) watch the server status using 'kamctl moni'

b) try to login with your SIP client as user 'admin' with password 'openserrw'

c) try adding new users using 'kamctl add '

8) default values (database url, users and passwords) are:

- DEFAULT_DB_URL="mysql://openser:openserrw@localhost/openser"

- r/w user: openser ; passwd: openserrw

- r/o user: openserro ; passwd: openserro

VERY IMPORTANT NOTE: for security reasons, do change the values of passwords after installation

 

4. Troubleshooting

Q: SIP requests are replied by openser with "483 Too Many Hops" or "513 Message Too Large"

A: In both cases, the reason is probably an error in request routing script which caused an infinite loop. You can easily verify whether this happens by watching SIP traffic on loopback interface. A typical reason for misrouting is a failure to match local domain correctly. If a server fails to recognize a request for itself, it will try to forward it to current URI in believe it would forward them to a foreign domain. Alas, it forwards the request to itself again. This continues to happen until value of max_forwards header field reaches zero or the request grows too big. Solutions is easy: make sure that domain matching is correctly configured. A quick way to achieve that is to introduce a config option to kamailio.cfg:

alias=domainname

where domainname shall be replaced with name of domain, which you wish to server and which appears in request-URIs.
