Hi all: It's my first mail to the community and I know that will be a great community to share knowledge. OS Debian 6.4 Kamailio 4.1 I have the same problem that Oliver Roth describes in http://lists.sip-router.org/pipermail/sr-users/2013-October/080096.html, but in Kamailio 4.1: Module carrierroute not working starting from version kamailio 4.1 trying to activate carrierroute in kamailio.cfg loadmodule "carrierroute.so" i get the following error when starting kamailio (5794) ERROR: <core> [sr_module.c:599]: load_module(): ERROR: load_module: could not open module </usr/local/lib64/kamailio/modules/carrierroute.so>: /usr/local/lib64/kamailio/modules/carrierroute.so: undefined symbol: cfg_set_error_function 0(5794) : <core> [cfg.y:3408]: yyerror_at(): parse error in config file /usr/local/etc/kamailio/kamailio.cfg, line 245, column 12-28: failed to load module ERROR: bad config file (1 errors) Any idea? Maybe him o someone has the solution. Thanks all for your great work.
