So why not add this to your dialplan?  You could then stuff the value into 
the userfield of the cdr record.


Example from: http://www.voip-info.org/wiki/view/Asterisk+func+sip_header
=========================================================================
To get Ip address of From (takes into account no caller id info i.e. no 
555 at 192.168.1.1 in the header):


exten => 1,1,Set(TESTAT=${CUT(SIP_HEADER(From),@,2)})
exten => 1,n,GotoIf($["${TESTAT}" != ""]?hasat)
exten => 1,n,Set(FROM_IP=${CUT(CUT(SIP_HEADER(From),>,1),:,2)})
exten => 1,n,Goto(gotip)
exten => 1,20(hasat),Set(FROM_IP=${CUT(CUT(CUT(SIP_HEADER(From),@,2),>,1),:,1)})
exten => 1,n(gotip),NoOp(Gateway IP is ${FROM_IP})
