SIPp 2.0

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.
SIPp project 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.
Other advanced features include support of IPv6, TLS, SIP authentication, conditional scenarios, UDP retransmissions, error robustness (call timeout, protocol defense), call specific variable, Posix regular expression to extract and re-inject any protocol fields, custom actions (log, system command exec, call stop) on message receive, field injection from external CSV file to emulate live users.
While optimized for traffic, stress and performance testing, SIPp can be used to run one single call and exit, providing a passed/failed verdict.
Last, but not least, SIPp has a comprehensive documentation available both in HTML and PDF format.
SIPp can be used to test many real SIP equipements like SIP proxies, B2BUAs, SIP media servers, SIP/x gateways, SIP PBX, ... It is also very useful to emulate thousands of user agents calling your SIP system.
Enhancements:
- New: Statistical (conditional) branching feature. See
- http://sipp.sf.net/doc/reference.html#Randomness+in+conditional+branching.
- New: 3PCC extended mode - see
- http://sipp.sourceforge.net/doc/reference.html#3PCC+Extended
- Tool: monitor remote SIP servers through SNMP - see
- http://sipp.sourceforge.net/wiki/index.php/Getting_feedback_from_the_server
- Enh: extends the -aa option to UPDATE messages
- Enh: changes in the compilation with external libs - useful for the package
- generation system
- Enh: Allow sampling from a Weibull distribution for pause duration
- Enh: use stat_delimiter for the trace_rtt option and include number that is
- being reported.
- Enh: Add repeat_rtd keyword for repeated RTD calculations
- Enh: Handle stripping Control-M characters from multi-valued headers in
- get_header
- Enh: Update the clock_tick more frequently so that we have a higher timer and
- statistics resolution
- Enh: for option that take a time as argument - allow them to be specified using
- seconds or milliseconds
- Enh: fail when parsing a scenario that has pcap if pcap is not enabled
- Enh: print the actual location of the error log file and the error condition
- (if any) on creation
- Enh: fail when parsing a scenario that enables authentication if SSL is not
- enabled
- Enh: Makefile - include EXTRAENDLIBS keyword so that libraries can be appended
- to the list after SSL Enh: Add regexp_match argument to the receive command for
- universal catching
- Enh: remote control: increase the allowed number of control sockets.
- Enh: 3pcc extended: clean the reach of the allowed number of local twin sockets
- Enh: amelioration of statistic computing
- Enh regexp: add case_indep, occurence and start_line options for the hdr
- matching case
- Enh: Stats: Use RTDs that are precise to the microsecond in -trace_rtt, and
- improve the consistency between trace_rtt and the averages
- Enh: Only include RTDs that are actually used in the CSV output
- Enh: Allow loss percentages less than 1 and also a global command line option to
- specify that packets should be lost at a given percentage
- Fix: fix for -t un error for non-IPv6 platform like win32 - Unable to bind UDP
- socket, errno = 106 (Address family not supported by protocol)
- Fix: Do not initialize the screen library in background mode
- Fix: allow having an optional recv before a recvCmd
- Fix: Authentication: allow [fieldn] values for the [authentication] field
- Fix: updated support of short header forms
- Fix: small bug fix to the micrortt.diff which is required for the initial call
- rate to work properly
- Fix:Allow the code to compile with -Wall -Werror on Linux
- Fix: empty line was generated when [routes] keyword was used and proxy did not
- record-route
- Fix: pcap on HPUX; Fix: Simple fixes identified with valgrind
- Fix: 3pcc extended: problem when quitting
- Fix: regexp: add a warning when the specified header is not present in the
- received message
- Fix: pcap: destroy the send packets thread properly even if the sendto failed
- Fix: bug in regexp due to an incomplete commit (rev 172) - remove some debugging
- traces in message log file
- Fix: bugs on retransmission counters and on cookies for optional messages
- Fix: Incorrect branch in automatic ACK answering to unexpected >= 400 responses,
- as well as automatic CANCEL - in such cases, branch must be identical to the
- branch of the initial INVITE request
- Fix: 3pcc extended: clean up when screen exit. Fix: stop logging when the
- maximum allowed file size is reached (avoid core dump)
- Fix: incomplete Via header in automatic responses when aborting calls
- Fix: -h: -key parameter
- Fix: 3pcc/3pcc extended modes: closes twin sockets properly when twin instance
- exits, to break the poll() loop and avoid the print of empty messages
- Fix: in 3pcc/3pcc extended modes: send BYE/CANCEL before exit due to other twin
- instance exit
- Fix: force exit when pressing q twice (Q press can still be used)
- Fix: Aka authentication for synchro case, also added password len as password
- for authentication might contain char Fix: possible core dump in SDP parser
- Fix: accept up to the 5 defined RTDs (previously would only accept one less)
- Fix: Fail if there is an invalid repartition table specification - previous
- behavior was a core dump
- Fix: added -users option to the parameter table
- Fix: change option description to match timed options
- Fix: trace_err did not work in background mode
- Fix: bug when testing the presence of the 3PCC compilation flag
- Fix: bug in -r -rp option
