my proxy is listening at udp/tcp ip:port 192.98.102.30:5060 and my
script has this for in-dialog requests:
route [IN_DIALOG_REQUEST] { # handle in-dialog request
if (!loose_route()) {
xlog("L_INFO", "Loose route failed on $hdr(route)\n");
...
exit;
};
xlog("L_INFO", "destination uri after loose_route: <$du>\n");
if i send to my proxy with sipp this in-dialog bye:
<?xml version="1.0" encoding="ISO-8859-1" ?>
<!DOCTYPE scenario SYSTEM "sipp.dtd">
<scenario name="In-dialog BYE">

i correctly get to syslog:
Apr 1 20:47:28 siika /usr/sbin/sip-proxy[9583]: INFO: destination uri after
loose_route: <<null>>
that is, the proxy removed both route uris that pointed to itself from
the route set leaving empty $du.
however, if i send to my proxy with sipp this in-dialog bye (where the
only difference to the previous one is request uri that now contains alias
param):
<?xml version="1.0" encoding="ISO-8859-1" ?>

i get to syslog:
Apr 1 20:51:20 siika /usr/sbin/sip-proxy[9540]: INFO: destination uri after
loose_route: <sip:192.98.102.30;transport=tcp;r2=on;lr;n1>
can someone explain, how it is possible that when request uri changes,
loose_route() does not anymore consume both route uris that point to the
proxy itself? could this be a bug in loose_route()?
