Hello Sergiu, Thank you for the pointer, the line 1576 is: get_profile_size("callee", "$avp(custid)", "$avp(concurrent)"); That is where Kamailio refuses to start.... And as you mentioned my error in the IF statement after correction you pointed out, Kamailio still refuses on the fact that the profile <callee> was not defined... Dec 4 13:42:50 proxy01 /usr/local/sbin/kamailio[75008]: CRITICAL: dialog [dialog.c:391]: fixup_profile(): profile <callee> not defined Dec 4 13:42:50 proxy01 /usr/local/sbin/kamailio[75008]: ERROR: <core> [core/route.c:1166]: fix_actions(): fixing failed (code=-6) at cfg:/usr/local/etc/kamailio/kamailio.cfg:1576 Dec 4 13:42:50 proxy01 systemd[1]: kamailio.service: Main process exited, code=exited, status=255/n/a Dec 4 13:42:50 proxy01 systemd[1]: kamailio.service: Failed with result 'exit-code'. Does anyone else maybe have an idea on where I go wrong?
