[Freeswitch-users] need more variables which xml_curl module sends

Hello FS users, I search some way for recieving more variables which my php script recieves in array - $_REQUEST from xml_curl module (it is intralanman's scripts) in case of recieving sip message - REGISTER from some sip device. I see list of variables:http://wiki.freeswitch.org/wiki/Mod_xml_curl#Authorization But, I need more. For example I need to know source sip port of endpoint. Also I have to know full SIP contact header from REGISTER request. Please advise.Thanks.
