ABOUT

VoIP perf

It is a SIP signaling performance testing application that can provide a server and a client.
It can produce latency stats at specified intervals in csv to measure the response time of any SIP endpoint.
It can also read a json configuration file and randomize numbers.

Docker quick start

quick start with docker

Linux Debian building from sources

see commands in Dockerfile

Example : starting a server

./voip_perf  \
   --local-port=5072 \     # server listening port
   --trying \              # when receiving invite 100 trying will be send
   --ringing \             # when receiving invite 183 will be sent
   --thread-count=4 \      # number of server threads created
   --delay=1500            # ringing delay in MS 1.5 second

Example : starting a client

This will send one INVITE to a randomise number starting with +1206?????? to server 1.1.1.1

./voip_perf \
  "sip:+1206???????@1.1.1.1" \ # target R-URI, <?> will be replaced by random digit
  --method="INVITE" \          # method
  --local-port=5072 \          # source port
  --caller-id="+1??????????" \ # user part of the From header, <?> will be replaced by random digit
  --count=1 \                 # total calls to send
  --proxy=2.2.2.2 \           # this will send the SIP message to a SIP proxy instead of the host in R-URI
  --duration=5 \              # send BYE after 5 seconds
  --call-per-second=500 \     # send 500cps
  --window=100000 \           # maximum amount of in progress calls
  --thread-count=1 \          # number of thread used
  --interval=1 \              # reporting interval, everyone second a line is added to voip_perf_stats.log with latency metrics
  --timeout 7200              # total run time , if all the requests where not send, voip_perf will stop and report scnenario timeout
# --verbose                   # runwith verbose logs

Example : starting a client with TLS

./voip_perf "sip:+1??????????@sip.domain.com:5061;transport=tls" \
    --local-port=5050 \
    --method="INVITE" \
    --caller-id="+1??????????" \
    --interval=1 \
    --count=20 \
    --call-per-second=10 \
    --window=25 \
    --thread-count=1 \
    --use-tls \
    --timeout 7200 \
    --tls-cert="tls/certificate.pem" \
    --tls-key="tls/key.pem" \
    --tls-calist="tls/ca_list.pem" \
    --conf="conf.json"
#    --verbose \

Example : config in json file

{
  "server" : [
    {
      "response" : [
        { "code" : 200,
          "reason" : "OK",
          "probability" : 0.6
        },
        { "code" : 404,
          "reason" : "Not found",
          "probability" : 0.3
        },
        { "code" : 0,
          "reason" : "drop/no response timeout",
          "probability" : 0.1
        }
      ]
    }
  ],
  "client": [
    {
      "extra-headers": {
        "Foo": "Bar",
        "Bar": "Foo"
      }
    },
    {
      "users": [
        {
          "ruri": "sip:12063??????@192.168.10.10",
          "extra-headers": {
            "Bar": "Open"
          }
        },
        {
          "ruri": "sip:12063??????@192.168.10.10",
          "extra-headers": {
            "Bar": "Close"
          }
        },
        {
          "ruri": "sip:12063??????@192.168.10.10",
          "extra-headers": {
            "VIP": "True",
            "Bar": "Open"
          }
        }
      ]
    }
  ]
}

Example : adding headers from a C header file

You can add custom headers in this file

include/custom_headers.h
