SIPp is a cost-free open source screening software and site visitors generator for the SIP protocol. It includes a couple essential SipStone person agent scenarios (UAC and UAS), establishes and releases various phone calls with the INVITE and BYE techniques, can read through personalized XML scenario data files (describing straightforward to quite advanced connect with flows), and can be made use of to take a look at numerous real SIP tools (these types of as SIP proxies, B2BUAs, SIP media servers, SIP/x gateways, SIP PBX, and additional). Finally, the SIPp device can emulate thousands of simultaneous user brokers, contacting into your procedure, to see how your network and SIP procedure handles really serious stress tests.
I want to clearly show you how to put in SIPp on Ubuntu Server 18.04 and then show some easy illustrations. Do take note, this instrument is command line only, so if you are seeking for a GUI for tests, look elsewhere.

What you want
In buy to make this perform, you have to have a thoroughly up to date Ubuntu Server 18.04 set up and a SIP technique to check. With that in position, let us install SIPp.
Put in dependencies
The very first thing to do is put in the important dependencies. Open a terminal window and problem the pursuing command:
sudo apt-get put in -y pkg-config dh-autoreconf ncurses-dev make-essential libssl-dev libpcap-dev libncurses5-dev libsctp-dev lksctp-equipment
If you really don’t currently have git set up, do so with the command:
sudo apt-get set up -y git
Put in SIPp
Now we’ll down load and install SIPp. To do this, we are going to make use of git with the command:
git clone https://github.com/SIPp/sipp.git
Modify into the newly designed listing with the command cd sipp. Make SIPp with the command:
./develop.sh --with-pcap --with-sctp --with-openssl
Copy the SIPp binary with the command:
sudo cp sipp /usr/neighborhood/bin/
Working with SIPp
You’re now prepared to use SIPp to test your SIP. The basic usage of SIPp is:
sudo sipp distant_host:port selections
To run SIPp with an embedded server circumstance (UAS), concern the command:
sudo sipp -sn uas
You should see the SIPp software functioning on your procedure (Determine A).
To stop the examination, strike the q important on your keyboard.
You can also build XML scenarios (for tests puposes). A primary state of affairs file will begin with:
And conclusion with:
To get a head begin on scenario files, you can export the created in files with the sipp command. Say you want to edit the UAC_PCAP situation. To do that, challenge the command:
sudo sipp -sd uac_pcap >> integrated_uac_pcap_scenario.xml
You should now see the circumstance file named integrated_uac_pcap_scenario.xml. Edit that file to fit your wants and then run it like so:
sudo sipp -i 192.168.1.203 -p 8832 -sf built-in_uac_pcap_circumstance.xml -l 1 -m 1 -r 1 -s 111 192.168.1.162
The adhering to describes the possibilities used:
- -l limit Restrict simultaneous calls (default: 3 * connect with_period (s) * price).
- -m phone calls End and exit soon after specified exams depend.
- -r fee Situation execution charge, default price = 10 situations per period of time, default interval = 1000 ms.
- -s services Set consumer element of the request URI (default: ‘service’). Replaces [service] tag in XML state of affairs file.
You could also develop an Alternatives.xml file with the adhering to content:
From: sipp tag=[call_number] Connect with-ID: [call_id] CSeq: 1 Possibilities Contact: Acknowledge: application/sdp Content-Length: ]]>
Conserve and near that file.
To send out the Solutions message (employing our Alternatives.xml file) 5 moments to firstname.lastname@example.org (assuming 192.168.1.203 is either a server or client producing use of the SIP protocol), the command would be:
sudo sipp 192.168.1.211 -sf Choices.xml -m 5 -s 30
To master a lot more about modifying and creating your individual scenarios, check out out the SIPp documentation on the subject matter.
Scratching the floor
We have only scratched the surface of SIPp screening. It is really a rather challenging screening software and one particular that does call for the administrator have a lot of understanding of the two the SIP protocol and the associated resources. I really advise likely through the SIPp documentation, prior to employing the tool. There is a good deal to read through, but at the time you have gone as a result of it, you’ll be equipped to use the command to anxiety exam your SIP-enabled network to see how well it fares versus major use.
