thanks Peter,
yes , i have followed the page :  http://wiki.freeswitch.org/wiki/Mod_lua/Serving_Configuration

my configurations as follow:
<configuration name="lua.conf" description="LUA Configuration"> <settings> <param name="xml-handler-script" value="register.lua"/> <param name="xml-handler-bindings" value="dialplan"/> </settings>
</configuration>
in register.lua script , i have authenticared and registered users usig lua script instead of using in-memory method,  so the sip header  initiatiate in lua script  as follow: (i don't now why  CSeq/contact/, etc left empty)...

Is this some kind of xml-generating script for register bindings (as in here: http://wiki.freeswitch.org/wiki/Mod_lua/Serving_Configuration)? If that’s the case, you have no session object, and you will have to follow the information on that wiki page instead.

Use session:getVariable("var") to read whatever channel variable you need. As Michael said, the SIP headers are stored like sip_header_name. For instance, to read the header Diversion:, use the variable sip_diversion.

Michael also mentions the info app, which is a good way to dump all channel variables for a channel, so you know exactly what you have available. To use this, just execute the app info in the dialplan.

See if you have a bunch of sip_xxx channel variables. Send the call to the info app and see what you've got.
