[sr-dev] Outbound flow failure handling merged to master

[Juha Heinanen]

hugh,

sometimes unregistering in event_route[tm:branch-failure] works fine,
e.g.:

Apr  6 09:39:00 siika /usr/sbin/sip-proxy[21504]: INFO: event_route[tm:branch-failure]
Apr  6 09:39:00 siika /usr/sbin/sip-proxy[21504]: INFO: Unregistering <sip:test at test.fi> with ruid <uloc-515fc1d4-53ff-2>

but sometimes looks like $T_reply_ruid is corrupted:

Apr  6 09:39:06 siika /usr/sbin/sip-proxy[21533]: INFO: event_route[tm:branch-failure]
Apr  6 09:39:06 siika /usr/sbin/sip-proxy[21533]: INFO: Unregistering <sip:test at test.fi> with ruid <ulo`
Apr  6 09:39:06 siika /usr/sbin/sip-proxy[21533]: WARNING: registrar [save.c:993]: AOR/Contact not found
Apr  6 09:39:06 siika /usr/sbin/sip-proxy[21533]: WARNING: Failed to unregister <sip:test at test.fi> with ruid <ulo`

the piece of config file producing the above is:

    if (t_check_status("(408|486)")) {
        xlog("L_INFO", "Unregistering <$avp(REQUEST_URI_AVP)> with ruid <$T_reply_ruid>\n");
        if (!unregister("location", "$avp(REQUEST_URI_AVP)",
                "$T_reply_ruid")) {
            xlog("L_WARN", "Failed to unregister <$avp(REQUEST_URI_AVP)> with ruid <$T_reply_ruid>\n");
        };
        ...

i added 486 (busy) to t_check_status just to ease testing.

in usrloc table ruid field values are correct, i.e., there is no value
"ulo`".
