	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=""
	pidfile="/var/run/kamailio2.pid"

	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

	In order to respond with a 200 OK response to the SIP OOPTION requests,
	the kamailio.cfg file needs to contain following section:
	Note: The following "kamailio.cfg" code sniplet is part of an XML section.
	Therefore it contains two & characters, which need to be replaced
	with two ampersand characters within "kamailio.cfg":

	if (is_method("OPTIONS") && ($ru=~"sip:monitor@.*")) {

	## If the method is an OPTIONS we are simply going to respond
	## with a 200 OK.

	</parameter>

	<parameter name="kamctlrc" unique="0" required="0">
	<longdesc lang="en">
	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 ressource 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 ressource 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 resoure agent for an example
	of parameter combinations in case that multiple instances are to be
	configured per cluster node.
