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

Normally, you should be able to build SIPp by using the provided build script: This:

  • checks out the gtest submodule
  • generates autotools files
  • runs configure
  • builds and runs the test suite
  • builds SIPp passes its arguments through to the configure script, so you can enable SSL, PCAP and SCTP support by calling ./ --with-pcap --with-sctp --with-openssl or ./ --full to enable all optional features.


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

Making a release

  • Update Tag release.
  • Download zip, autoreconf -vif, copy sipp.1, copy include/version.h.
  • Create tgz. Upload to github as "binary".


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:

  • SIPp uses GNU autotools, so changes to the build process should be done by editing and Then regenerate the files with autoreconf -ivf. (You will need your distribution's autotools and autoconf-archive packages installed for this.)

  • 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 your changes can be compiled on:
    • Linux,
    • Cygwin,
    • Mac OS X,
    • FreeBSD.
