Try this, it may work
<recv request="INVITE" crlf="true" rrs="true">
<action>
<ereg regexp="(Via.*)([[:cntrl:]][[:cntrl:]]Via:[^[:cntrl:]]*)"
search_in="msg"
check_it="true"
assign_to="1,2,3" />
</action>
</recv>
in your 180 response for the VIA statements, just put [$1] and nothing
more. The egrep for [$1] will have all the VIAs sent in from the INVITE
and it will have the complete VIAs structures.
Example:
<send>
<![CDATA[
SIP/2.0 180 RINGING
[$1] <-- this represents the VIA statements on the reply
[last_From:]
[last_To:]
[last_Call-ID:]
[last_Event:]
[last_CSeq:]
Content-Length: 0
]]>
</send>
