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

--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
