 <longdesc lang="en">
  Resource agent for the Kamailio SIP proxy/registrar.
  Multiple instances are possible when using following parameter combinations:
 
  Parameters for Kamailio instance 1:
     listen_address=192.168.159.128
     monitoring_ip=192.168.159.128
     proto=udptcp
     port=5060 
 
  Parameters for Kamailio instance 2:
     listen_address=192.168.159.128
     monitoring_ip=192.168.159.128
     proto=udp
     port=5070
     conffile=/etc/kamailio/kamailio2.cfg
     kamctlrc=""
 
  Only one instance can be monitored via the command "kamctl monitor"
  because the kamctl tool of kamailio 4.x is not designed for multiple
  instances. Therefore, the provided kamctrlrc file path needs to be 
  empty for instance 2, 3 ...
 
 Parameters for a third Kamailio instance:
     listen_address=192.168.159.128
     monitoring_ip=192.168.159.128
     proto=tcp
     port=5080

     The location of the "kamctlrc" file for the Kamailio instance.
     The file "kamctlrc" is the Kamailio configuration file for its "kamctl" control tool.
 
     This parameter only needs to be provided in case of using multiple Kamailio server
     instances on a single cluster node:
 
     In case that the parameter "kamctlrc" is not empty, this resource agent monitors
     the health state of the Kamailio server via the command "kamctl monitor 1". This 
     setting is recommended in case of using a single Kamailio server instance.
 
     In case that the parameter "kamctlrc" is empty, the resource agent does not
     monitor the health state of the Kamailio server instance via the "kamctl" command.
 
     Please note that the "kamctl" control command of Kamailio 4.x does not support 
     running multiple Kamailio instances on one host. Nevertheless this resource agent 
     does allow multiple Kamailio instances per host. The result of the "kamctl" 
     limitation in terms of number of Kamailio server instances is that the health 
     check via "kamctl monitor 1" can be configured for a single Kamailio instance
     only.
 
     Please refer to the long description of this resource agent for an example
     of parameter combinations in case that multiple instances are to be 
     configured per cluster node.
