Hi joerg,
If there are hops in ur sip network 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
[last_Call-ID:]
[last_CSeq:]
Contact: [field0] <sip:[EMAIL PROTECTED]:[local_port]>
[last_Record-Route:]
Content-Length: 0
]]>
</send>
Hope it will help u ..
