Hi,

I have problem with CPL. This is my config file for openser:
debug=3            # debug level (cmd line: -dddddddddd)
fork=yes           # Set to no to enter debugging mode
log_stderror=no    # (cmd line: -E) Set to yes to enter debugging mode

check_via=no	# (cmd. line: -v)
dns=no          # (cmd. line: -r)
rev_dns=no      # (cmd. line: -R)
port=5060
children=4
fifo="/tmp/openser_fifo"

#
# uncomment the following lines for TLS support
#disable_tls = 0
#listen = tls:your_IP:5061
#tls_verify = 1
#tls_require_certificate = 0
#tls_method = TLSv1
#tls_certificate =
"/build/buildd/openser-1.1.0/debian/openser/etc/openser/tls/user/user-cert.pem"
#tls_private_key =
"/build/buildd/openser-1.1.0/debian/openser/etc/openser/tls/user/user-privkey.pem"
#tls_ca_list =
"/build/buildd/openser-1.1.0/debian/openser/etc/openser/tls/user/user-calist.pem"

# -------------------------  request routing logic -------------------

# main routing logic

route{

	# initial sanity checks -- messages with
	# max_forwards==0, or excessively long requests
	if (!mf_process_maxfwd_header("10")) {
		sl_send_reply("483","Too Many Hops");
		exit;
	};

	if (msg:len >=  2048 ) {
		sl_send_reply("513", "Message too big");
		exit;
	};

	# we record-route all messages -- to make sure that
	# subsequent messages will go through our proxy; that's
	# particularly good if upstream and downstream entities
	# use different transport protocol
	if (!method=="REGISTER")
		record_route();

	# subsequent messages withing a dialog should take the
	# path determined by record-routing
	if (loose_route()) {
		# mark routing logic in request
		append_hf("P-hint: rr-enforced\r\n"); 
		route(1);
	};

	if (!uri==myself) {
		# mark routing logic in request
		append_hf("P-hint: outbound\r\n"); 
		# if you have some interdomain connections via TLS
		#if(uri=~"@tls_domain1.net") {
		#	t_relay("tls:domain1.net");
		#	exit;
		#} else if(uri=~"@tls_domain2.net") {
		#	t_relay("tls:domain2.net");
		#	exit;
		#}
		route(1);
	};

	# if the request is for other domain use UsrLoc
	# (in case, it does not work, use the following command
	# with proper names and addresses in it)
	if (uri==myself) {

		if (method=="REGISTER") {

			# Uncomment this if you want to use digest authentication
			#if (!www_authorize("openser.org", "subscriber")) {
			#	www_challenge("openser.org", "0");
			#	exit;
			#};
		        cpl_process_register();
			save("location");
			exit;
		};

		lookup("aliases");
		if (!uri==myself) {
			append_hf("P-hint: outbound alias\r\n"); 
			route(1);
		};

		# native SIP destinations are handled using our USRLOC DB
		if (!lookup("location")) {
			sl_send_reply("404", "Not Found");
			exit;
		};
		append_hf("P-hint: usrloc applied\r\n"); 
	};

	route(1);
}


route[1] {
	# send it out now; use stateful forwarding as it works reliably
	# even for UDP2TCP
	if (!t_relay()) {
		sl_reply_error();
	};
	exit;
and this is easy cpl script:

<?xml version="1.0" encoding="UTF-8"?>

<cpl>
  <incoming>
    <reject status="400" reason="Busy" />
  </incoming>
</cpl>

Upload of this cpl script to DB is correct, record in table "cpl" is created
for "user" but when I am calling to this "user", openser ignores this script
and phone is ringing.
I don't know what is problem, could somebody help me?
 thanks
                   Martin
