SIPp
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.
Other advanced features include support of IPv6, TLS, SCTP, 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.
SIPp can also send media (RTP) traffic through RTP echo and RTP / pcap replay. Media can be audio or video.
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 various real SIP equipment 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.

sipp – Traffic generator for the SIP protocol
root@kali:~# sipp
Usage:
sipp remote_host[:remote_port] [options]
Available options:
-v : Display version and copyright information.

By default, the URI is composed of
remote_ip:remote_port.
-au : Set authorization username for authentication challenges.
Default is taken from -s argument
-ap : Set the password for authentication challenges. Default
is 'password'
-base_cseq : Start value of [cseq] for each call.
-bg : Launch SIPp in background mode.
-bind_local : Bind socket to local IP address, i.e. the local IP
address is used as the source IP address. If SIPp runs
in server mode it will only listen on the local IP
address instead of all IP addresses.

-ci : Set the local control IP address
-cp : Set the local control port number. Default is 8888.
-d : Controls the length of calls. More precisely, this
controls the duration of 'pause' instructions in the
scenario, if they do not have a 'milliseconds' section.
Default value is 0 and default unit is milliseconds.
-deadcall_wait : How long the Call-ID and final status of calls should be
kept to improve message and error logs (default unit is
ms).
-default_behaviors: Set the default behaviors that SIPp will use. Possbile
values are:
- all Use all default behaviors
- none Use no default behaviors
- bye Send byes for aborted calls
- abortunexp Abort calls on unexpected messages
- pingreply Reply to ping requests
If a behavior is prefaced with a -, then it is turned
off. Example: all,-bye
-error_file : Set the name of the error log file.
-error_overwrite : Overwrite the error log file (default true).
-f : Set the statistics report frequency on screen. Default is
1 and default unit is seconds.
-fd : Set the statistics dump log report frequency. Default is
60 and default unit is seconds.
-i : Set the local IP address for 'Contact:','Via:', and

the scenarios.
First line of this file say whether the data is to be
read in sequence (SEQUENTIAL), random (RANDOM), or user
(USER) order.
Each line corresponds to one call and has one or more
';' delimited data fields. Those fields can be referred
as [field0], [field1], ... in the xml scenario file.
Several CSV files can be used simultaneously (syntax:

Create an index of file using field. For example -inf
users.csv -infindex users.csv 0 creates an index on the
first key.

address from which the client will send its messages.
If this option is omitted and the '-t ui' option is
present, then field 0 is assumed.

are finished before SIPp exits.
Example: kill -SIGUSR1 732

<scenario_name>_<pid>_screens.log file. Especially useful
in background mode to know what the current status is.
Example: kill -SIGUSR2 732

option) is reached, sipp exits with one of the following exit
code:
0: All calls were successful
1: At least one call failed
97: exit on internal command. Calls may have been processed
99: Normal exit without calls processed
-1: Fatal error

Use the '-h stat' option for a detailed description of
the statistics file content.
-trace_counts : Dumps individual message counts in a CSV file.
-trace_rtt : Allow tracing of all response times in <scenario file
name>_<pid>_rtt.csv.
-trace_logs : Allow tracing of <log> actions in <scenario file
name>_<pid>_logs.log.
-users : Instead of starting calls at a fixed rate, begin 'users'
calls at startup, and keep the number of calls constant.
-watchdog_interval: Set gap between watchdog timer firings. Default is 400.
-watchdog_reset : If the watchdog timer has not fired in more than this
time period, then reset the max triggers counters.
Default is 10 minutes.
-watchdog_minor_threshold: If it has been longer than this period between watchdog
executions count a minor trip. Default is 500.
-watchdog_major_threshold: If it has been longer than this period between watchdog
executions count a major trip. Default is 3000.
-watchdog_major_maxtriggers: How many times the major watchdog timer can be tripped
before the test is terminated. Default is 10.
-watchdog_minor_maxtriggers: How many times the minor watchdog timer can be tripped
before the test is terminated. Default is 120.
-3pcc : Launch the tool in 3pcc mode ("Third Party call
control"). The passed ip address is depending on the
3PCC role.
- When the first twin command is 'sendCmd' then this is
the address of the remote twin socket. SIPp will try to
connect to this address:port to send the twin command
(This instance must be started after all other 3PCC
scenarii).
Example: 3PCC-C-A scenario.
- When the first twin command is 'recvCmd' then this is
the address of the local twin socket. SIPp will open
this address:port to listen for twin command.
Example: 3PCC-C-B scenario.
-tdmmap : Generate and handle a table of TDM circuits.
A circuit must be available for the call to be placed.
Format: -tdmmap {0-3}{99}{5-8}{1-31}
-key : keyword value
Set the generic parameter named "keyword" to "value".
-set : variable value
Set the global variable parameter named "variable" to
"value".
-dynamicStart : variable value
Set the start offset of dynamic_id varaiable
-dynamicMax : variable value
Set the maximum of dynamic_id variable
-dynamicStep : variable value
Set the increment of dynamic_id variable
Signal handling:
SIPp can be controlled using posix signals. The following signals
are handled:
USR1: Similar to press 'q' keyboard key. It triggers a soft exit
of SIPp. No more new calls are placed and all ongoing calls
are finished before SIPp exits.
Example: kill -SIGUSR1 732
USR2: Triggers a dump of all statistics screens in
<scenario_name>_<pid>_screens.log file. Especially useful
in background mode to know what the current status is.
Example: kill -SIGUSR2 732
Exit code:
Upon exit (on fatal error or when the number of asked calls (-m
option) is reached, sipp exits with one of the following exit
code:
0: All calls were successful
1: At least one call failed
97: exit on internal command. Calls may have been processed
99: Normal exit without calls processed
-1: Fatal error
-2: Fatal error binding a socket
Example:
Run sipp with embedded server (uas) scenario:
./sipp -sn uas
On the same host, run sipp with embedded client (uac) scenario
./sipp -sn uac 127.0.0.1
sipp Usage Example
Run sipp using the embedded server (-sn uas) scenario:
root@kali:~# sipp -sn uas
