=============================
    If there are hops in ur sip
network<http://osdir.com/ml/telephony.sipp.user/2008-05/msg00050.html#>then
u have to fetch the values of via header field from INVITE  and
replace
in 180 ringing.
Here I give u the sample, how I m using...


 <recv request="INVITE" rrs="true" >
     rrs="true" crlf="true"
     <action>
    <ereg regexp="(SIP.*branch=[^[:space:]]*)" search_in="hdr" occurence="2"
header="Via:"  assign_to="3,6" />
    <ereg regexp="(SIP.*branch=[^[:space:]]*)" search_in="hdr" occurence="1"
header="Via:"  assign_to="8,7" />
    <ereg regexp=".*" search_in="hdr" occurence="1" header="Record-Route:"
assign_to="9" />
    <ereg regexp="INVITE sip:([[:alnum:]]*)" search_in="msg"
assign_to="10,11" />

   </action>
   </recv>
  <send>
    <![CDATA[

      SIP/2.0 180 Ringing
      Via: [$7]
      Via: [$6]
      [last_From:]
      [last_To:];tag=[call_number]-INV-UAS

      Contact: [field0] <sip:[EMAIL PROTECTED]:[local_port]>
      [last_Record-Route:]
      Content-Length: 0

    ]]>
