Hi Jeff,
Well, life sucks.....You see, the UA you use is re-ordering the URI
params...This is perfectly allowed from RFC point of view, but is
bullshit in real life. So your UA is compliant, but not fairplay :)....
The only solution to this is to extend the "SIP URI matching" from
simple string comparison, to RFC-wise comp - parsing the URI, checking
username, domain, params, etc.....I tried to avoid this as much as
possible as it BS to me....
Regards,
Bogdan

Not quite sure what to say about this one.

Indeed! I hadn't noticed the difference in the dlg vs req sections of
the debug message.
I shall try exactly as you suggest. Thanks.

ACK in loose_route
Hello Jeff,
It's not that the dialog is already torn down by the time the BYE gets
to that particular portion of script.
It's complaining about the fact that at the dialog creation, the route
had the "lr=on" parameter, and at BYE time, the parameter has been
stripped and set
just to "lr".
This should not happen in a regular scenario, as other SIP entities
should not explicitly modify the content of Route headers recorded at
Invite time.
You could try to check the enable_full_lr ( [1] ) parameter, and
onlyattach "lr" instead of "lr=on", and see if this fixes the behavior.

Hello,
I'm trying a new chunklet of config in loose_route(). I believe this
came from a documentation page somewhere, so I don't pretend to take
credit for the concept.
# Clean up dialog data if necessary
if ($DLG_status!=NULL && !validate_dialog()) {
xlog("L_INFO", "Unable to validate
dialog, fixing - $hdr(CSeq) on $ci\n");
fix_route_dialog();
}
I send the first batch of pseudo-production traffic through this
config today and I ended up with a metric ton of:
ERROR:dialog:dlg_validate_dialog: Check failed for routenumber 0.
req=[sip:<opensips-IP?;lr;ftag=23ddd50-0-13c4-1f179b-78884527-1f179b;did=45b.b972314],dlg=[sip:<opensips-IP>;lr=on;ftag=23ddd50-0-13c4-1f179b-78884527-1f179b;did=45b.b972314]
And, the xlogs from the above line:
Unable to validate dialog, fixing - 3 BYE on <callid>
It showed up on a number of BYEs and ACKs. My dialog module config
is as follows:
# ----- dialog params -----
modparam("dialog", "dlg_flag", 4)
modparam("dialog", "bye_on_timeout_flag", 4)
modparam("dialog", "default_timeout", 21600)
modparam("dialog|sst", "timeout_avp", "$avp(s:dialog_timeout)")
modparam("dialog", "dlg_extra_hdrs", "Hint: dialog expired\r\n")
modparam("dialog", "dlg_match_mode", 1) # 0 = DID_ONLY; 1 = DID
first, SIP second; 2 = SIP only
modparam("dialog", "db_url", "mysql://osuer:ospass@dbcluster/osdb")
modparam("dialog", "table_name", "dialog_1")
modparam("dialog", "db_mode", 1) # 1 = Realtime to DB; 2 = delayed;
3 = on shutdown
modparam("dialog", "profiles_with_value", "711calls; 729calls; calls")
create_dialog() runs on all initial INVITEs.
Is this type of behavior anything close to normal? What might cause
it? My immediate fix is to simply comment out this portion of the
config, but I'm afraid I might be masking a larger issue. Any
suggestions would be great.
Just had a thought as I was about to send this email. Perhaps this
is because by the time the BYE gets to this portion of the script,
the dialog is already torn down? Could it be that simple, just add
"if !(is_method("BYE") || is_method("ACK"))" to the top line of this
config portion?
