[SR-Users] problem with LRKProxy module

Hello I have problem with lrkproxy module. First, I installed the packages from the link below : https://github.com/mojtabaesfandiari/pylrkproxy And the service was properly listened to the local ip (192.168.51.106:22333 ). In the next step, the parameters were added to the kamalio.cfg file : loadmodule "lrkproxy.so" modparam("lrkproxy", "lrkproxy_sock", "udp:192.168.51.106:22333") I also changed the /etc/pylrkproxy/pylrkproxy.ini to set local ip. But when I make a call, the ip inside the sdp not change. And the following error is displayed in the syslog: Sep 4 07:18:05 debian /usr/local/sbin/kamailio[1724]: INFO: {1 2 INVITE NzA0NmU0YTYwNWNkNzAwOWJiOTUyOWQ5ODhjNjRhNzk.} lrkproxy [lrkproxy.c:1507]: lrkproxy_force(): Here is SIP_REQUEST & METHOD_INVITE Sep 4 07:18:05 debian /usr/local/sbin/kamailio[1724]: ERROR: {1 2 INVITE NzA0NmU0YTYwNWNkNzAwOWJiOTUyOWQ5ODhjNjRhNzk.} lrkproxy [lrkproxy.c:1084]: select_lrkp_node(): script error -no valid set selected Sep 4 07:18:05 debian /usr/local/sbin/kamailio[1724]: ERROR: {1 2 INVITE NzA0NmU0YTYwNWNkNzAwOWJiOTUyOWQ5ODhjNjRhNzk.} lrkproxy [lrkproxy.c:1513]: lrkproxy_force(): can't ping any lrk proxy right now.
