[SR-Users] Syntax error - custom parameter

Hi all, I'm getting this error when using custom parameters and I don't why. when I use #!define WITH_ASTERISK the script throws the below error and when I remove the #!define WITH_ASTERISK the script loads without errors. I'm running kamailio-3.1.4-2.1.i386.rpm on Centos 5.6 Does anyone know why this might be happening? parse error in config file //etc/kamailio/kamailio.cfg, line 123, column 16: syntax error 0(2907) : <core> [cfg.y:3412]: parse error in config file //etc/kamailio/kamailio.cfg, line 123, column 16: unknown config variable 0(2907) : <core> [cfg.y:3409]: parse error in config file //etc/kamailio/kamailio.cfg, line 123, column 17-19: ERROR: bad config file (3 errors) kamailio.cfg::: lines 122-127 #!ifdef WITH_ASTERISK asterisk.bindip = "127.0.0.1" desc "Asterisk IP Address" asterisk.bindport = "5070" desc "Asterisk Port" kamailio.bindip = "209.15.226.21" desc "Kamailio IP Address" kamailio.bindport = "5060" desc "Kamailio Port" #!endif # This follows as described here: http://by-miconda.blogspot.com/2010/04/kamailio-30x-dyk-07-custom-cfg.html Thanks in advance
