[SR-Users] kamailio 3 and cpl - 483 too many hops

I am trying to incorporate a cpl script for testing purposes with kamailio 3 but have been met with failure with each try. Test scenario I have two sip phones registered to kamailio successfully (I can make phone calls between the two phones). The CPL XML is as follows: <?xml version="1.0" encoding="UTF-8"?<cpl <incoming <location clear="yes" url="sip:1000@192.168.254.144<sip%3A1000@192.168.254.144>" <log comment="cpl-log - just location" / </location </incoming</cpl This compiled successfully and is populating the cpl table in the openser database. When I call this from kamailio.cfg I get the 483 (Too many hops) error. If someone could spot an obvious error, I would appreciate it. The current kamailio.cfg file is as follows: ------------------ debug=8 log_stderror=yes memdbg=5 memlog=5 log_facility=LOG_LOCAL0 fork=yes children=4 /* uncomment the next line to disable TCP (default on) */ disable_tcp=yes /* uncomment the next line to disable the auto discovery of local aliases based on revers DNS on IPs (default on) */ auto_aliases=no port=5060 /* uncomment and configure the following line if you want Kamailio to bind on a specific interface/port/proto (default bind on all available) */ listen=udp:192.168.254.144:5060 ####### Custom Parameters ######### #
