In your Kamailio configuration file you have to load jsonrpcs module and configure it. See:

• http://kamailio.org/docs/modules/stable/modules/jsonrpcs.html

The configuration related to JSONRPC for SIREMIS resides in file:

    siremis/modules/sipadmin/service/siremisJRCommands.xml

The content can look like:

<?xml version="1.0" standalone="no"?>
<PluginService Name="siremisJRCommands" Package="asipto" Class="siremisJRCommands">
    <JRConfig name="JRConfig" type="unixsock" mode="rich">

The IP, Port and URL path for Kamailio's JSONRPC socket (default is Kamailio's IP and SIP port) has to be set in RSocket.

In case you want to have a drop-down menu with JSONRPC commands, fill in new ‘cmd’ tags in ‘JRCommands’ node.
