FreeSWITCH call generator for performance tests

This is a simple dialer that connects to FreeSWITCH via event socket and originates calls at a given interval.

The script subsututes the question mark signs (?) with random digits in caller ID and the destination number.

There are two ways to specify the call destination:

Loopback endpoint

If used with --content and --dest options, the dialer originates the calls into the specified context via loopback endpoint. For example, the following contexts will forward all calls to some remote servers:

<!-- File: /etc/freeswitch/dialplan/dialer.xml -->
<include>
  <context name="dialer01">
    <extension name="to_sbc">
      <condition>
        <action application="set" data="sip_h_X-Asterisk-AccountNo=X839546"/>
        <action application="bridge"
                data="sofia/external/${destination_number}@203.0.113.55"/>
      </condition>
    </extension>
  </context>
</include>

Keep in mind that the default limit of sessions per second in FreeSWITCH is 30 (sessions-per-second parameter in autoload_configs/switch.conf.xml). Because of the loopback endpoint, each call occupies 3 channels, and this results in 10 calls per second maximum.

For example, the following command would start 100 calls, and each call would last 10 minutes:

perl /opt/freeswitch-perf-dialer/dialer.pl \
  --ncalls=100 --cps=9 --duration=600 --context=dialer01 \
  --dest='01234?????'

Endpoint string

You can specify explicitly the endpoint string. In case of SIP endpoints, that will instruct FreeSWITCH to use a specified SIP profile and gateway for example:

perl /opt/freeswitch-perf-dialer/dialer.pl --cid='+3333???????' \
 --endpoint='sofia/external/+777???????@10.250.250.23' --cps=5 --forever
 

perl /opt/freeswitch-perf-dialer/dialer.pl --cid='+3333???????' \
 --endpoint='sofia/gateway/voxbeam/+777???????' --cps=5 --forever

Usage

# perl /opt/freeswitch-perf-dialer/dialer.pl --help
Usage: /opt/freeswitch-perf-dialer/dialer.pl [options...]
Options:
  --fs_host=HOST    [127.0.0.1] FreeSWITCH host
  --fs_port=PORT    [8021] FreeSWITCH ESL port
  --fs_password=PW  [ClueCon] FreeSWITCH ESL password
  --cid=NUMBER      [12126647665] caller ID
  --dest=NUMBER     [13115552368] destination number
  --context=NAME    [public] FreeSWITCH context name
  --endpoint=STRING destination endpoint
  --duration=N      [60] call duration in seconds
  --ncalls=N        [10] total number of calls
  --cps=N           [10] rate in calls per second
  --play=STRING     [local_stream://moh] playback argument
  --help            this help message

If endpoint is specified, --dest and --context are ignored.
Otherwise, the call is sent to the loopback endpoint with the specified
context and destination number
