This is the SIPp package. Please refer to the webpage for details and documentation.

Normally, you should be able to build SIPp by using CMake:

cmake .

The SIPp master branch (3.7.x) requires a modern C++11 compiler.

There are several optional flags to enable features (SIP-over-TLS, SIP-over-SCTP, media playback from PCAP files and the GNU Statistical libbraries for random distributions):


Static builds

SIPp can be built into a single static binary, removing the need for libraries to exist on the target system and maximising portability.

This is a fairly complicated process, and for now, it only works on Alpine Linux.

To build a static binary, pass -DBUILD_STATIC=1 to cmake.


I try and be responsive to issues raised on Github, and there's a reasonably active mailing list.

Making a release

  • Update Tag release.
  • Make sipp.1 by calling help2man --output=sipp.1 -v -v --no-info --name='SIP testing tool and traffic generator' ./sipp
  • Copy sipp.1, copy $bindir/version.h to include/version.h.
  • Create sipp-VERSION.tar.gz with subdirectory sipp-VERSION. Upload to github as "binary".
  • Run sudo docker build -t sipp-build docker && sudo docker run -it -v $PWD:/src sipp-build to create a static binary. Upload this to Github as well.


SIPp is free software, under the terms of the GPL licence (see the LICENCE.txt file for details). You can contribute to the development of SIPp and use the standard Github fork/pull request method to integrate your changes integrate your changes. If you make changes in SIPp, PLEASE follow a few coding rules:

  • Please stay conformant with the current indentation style (4 spaces indent, standard Emacs-like indentation). Examples:

    if (condition) {        /* "{" even if only one instruction */
        f();                /* 4 space indents */
    } else {
        char* p = ptr;      /* C++-style pointer declaration placement */
  • If possible, check that your changes can be compiled on:

    • Linux,
    • Cygwin,
    • Mac OS X,
    • FreeBSD.
