OpenSIPS Development

GVenture Technology takes on a pleasant ride to develop OpenSIPS applications. A company that will overcome all issues in one place in no time. We will provide vicinity to make yourself convenient and to have carefree talk to tell us about your project, and then we can offer you all the bits and pieces essential for it.

Let us talk about OpenSIPS. OpenSIPS (Open SIP Server) is a developed Open Source implementation of a SIP server that runs on Linux platforms and plays in the infrastructure of an Internet Telephony Service Provider, and it includes application-level functionality. OpenSIPS, as a SIP server, is the main component of any SIP-based VoIP solution. With a very elastic and customized routing engine, OpenSIPS unifies voice, video, IM, and presence services in a highly efficient way, thanks to its scalable (modular) design.


Features of OpenSIPS:
  • Straight interconnection with PSTN gateways
  • IP Black-lists
  • Dialogue support
  • Plug/Play module interface
  • XCAP support for Presence Agent
  • Notable extension repository


Why use OpenSIPS?
  • No vendor trap
  • Faster development cycle
  • Split work between parties
  • Easy synchronization with the mainstream via contributions ⇒ Unified effort for the development
  • Performance and flexibility


  • Since OpenSIPS is known to work on most nix-based systems, installing and running OpenSIPS requires some very basic Linux knowledge.
  • Also, since OpenSIPS is a SIP proxy, you will most likely need some basic SIP knowledge to deploy/debug OpenSIPS in some more advanced scenarios.
  • Last but not least, you will need some basic programming logic knowledge. The OpenSIPS configuration file is text-based and written in an OpenSIPS custom language similar to the C language.


  • gcc / suncc / icc : gcc >= 2.9x; 4.[012] 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
  • libsctp if you want to compile the SCTP support
  • libmysqlclient & libz (zlib) -libs and devel headers- if you want mysql DB support (the db_mysql module)
  • libpq / postgresql -libs and devel headers- if you want postgres DB support (the db_postgres module)
  • unixodbc -libs and devel headers- if you want unixodbc DB support (the db_unixodbc module)
  • libexpat if you want the jabber gateway support (the jabber module) or the XMPP gateway support
  • libxml2 if you want to use the cpl-c (Call Processing Language) or the presence modules (presence and pua*)
  • libradius-ng -libs and devel headers- if you want to use functionalities with radius support – authentication, accounting, group support, etc
  • unixodbc – libs and devel headers – if you want UNIXODBC support as DB underlayer
  • libxmlrpc-c3 – libs and devel headers – if you want to have XML-RPC support for the Management interface (MI)
  • libperl – libs and devel headers – if you want PERL connector to support perl scripting from you config file (perl module)
  • libsnmp9 – libs and devel headers – if you want SNMP client functionality (SNMP AgentX subagent) for opensips
  • libldap libs and devel headers v2.1 or greater – if you want LDAP support
  • libconfuse and devel headers – if you want to compile the carrierroute module


  • cd /usr/src/
  • yum install bison bison-devel ncurses ncurses-devel zlib zlib-devel openssl openssl-devel gnutls-devel gcc gcc-c++ mysql-server mysql-client which flex make
  • Download opensips (Opensips 1.5 wget
  • tar -xzf opensips-1.5.0-tls_src.tar.gz
  • make all
  • make install
  • make config

By following the above two processes, we have installed the opensips server on our system. Now, we have to configure the server corresponding to our requirement.

The above configuration is sampled corresponding to a load-balanced format where calls are forwarded to different gateway corresponding to our requirements and gateway availability.
