SIPp 3.7.2

SIPp is a free Open Source test tool / traffic generator for the SIP protocol. It includes a few basic SipStone user agent scenarios (UAC and UAS) and establishes and releases multiple calls with the INVITE and BYE methods. It can also reads custom XML scenario files describing from very simple to complex call flows. It features the dynamic display of statistics about running tests (call rate, round trip delay, and message statistics), periodic CSV statistics dumps, TCP and UDP over multiple sockets or multiplexed with retransmission management and dynamically adjustable call rates.

3.7.217 Nov 2023 09:45 minor feature: Remove fprintf causing log spam Since #521, prepare_pkts may be called. on every call, not just on startup. This means that the log it prints to. Stderr is very visible and may cause performance problems. This commit. Removes it.
3.7.120 May 2023 03:20 minor feature: Allow build to proceed if gtest is missing Allow build to proceed if gtest is missing. Commit changes file.
3.6.117 Sep 2020 03:15 minor feature: CMake is now used as build environment: autoconf and friends are gone (#430, by Rob Day). See build.sh for CMake invocations. For a full build, do: Cmake. -DUSE_GSL=1 -DUSE_PCAP=1 -DUSE_SSL=1 -DUSE_SCTP=1 Make -j4 . Consistently unescape XML attributes when loading scenario (#458, by Steve Frécinaux). Buffer overflow in screen output. Nonce count in auth headers (#421, by Cody Herzog). Parser warning when trying to access 0-byte SDP body. Pcapplay on FreeBSD (#434, by Rob Day). Improve build validation (#424, by Stanislav Litvinenko), a few compiler, a few ncurses, build cleanup after CMake (#443, #442, by Orgad Shaneh) and libtinfo linker (Jeannot Langlois). Improve provided sipp.dtd file (#425, by David M. Lee), and XML by Rob Day. Make it easier to deal with large SIP packets by adding an optional CPPFLAGS=-DSIPP_MAX_MSG_SIZE=262144 flag (#422, by Cody Herzog).
3.7-dev02 Sep 2020 10:25 minor feature: Automatic filenames (trace files, error files, etc..) are now created in the current working directory instead of in the directory of the scenario file. Only validates SSL certficate if CA-file is separately specified!. Angle brackets and need to be escaped inside XML attributes. See #414. So, not regexp=" *" but regexp=" * lt;(sip:*) gt;". routes header in UAS scenario's. (, reported by Stefan Mititelu.). last_Keyword does not search in SIP body anymore (#207, reported by Zoltan). Added PAGER by default to the extremely large sipp help output. Removed unused RTPStream code concerning video streams. Also consolidated the rtpstream audio port usage to reuse the global media_port instead of the rtpstream_audio_port . Also the -min_rtp_port and -max_rtp_port options have been removed. Advantages: cleaner code, fewer scenario variables. Drawbacks: possible ICMP port unreachable messages for RCTP and video. Also, no easy way to discern different streams if you want to bombard a single UAS with multiple RTP streams. Add play_dtmf code originally from https://sourceforge.net/p/sipp/patches/50/ (Dmitry Kunilov), then pull #82 and then #141. Compile with pcap-play support, and use it by adding similar to how you use play_pcap_audio. Add RTP payload 96 in your SDP: m=audio media_port RTP/AVP 0 96 97 a=rtpmap:0 PCMU/8000 a=rtpmap:96 telephone-event/8000 a=fmtp:96 0-15 a=rtpmap:97 no-op/8000 Exec syntax is where digits can be one or more of "0123456789#*ABCD" and length defaults to 200 and must be between 50 and 2000. Instead of digits a field... keyword is also accepted. Make sure you add enough after play_dtmf. .
