Hi Jeff,<br>
<br>
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
:)....<br>
<br>
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....<br>
<br>
Regards,<br>
Bogdan<br>

Hello Jeff,<br>
<br>
It's not that the dialog is already torn down by the
time the BYE gets
to that particular portion of script.<br>
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 <br>
just to "lr".<br>
<br>
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. <br>
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.<br>

<div>Hello,</div>
<div><br>
</div>
<div>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.</div>

<div>I send the first batch of pseudo-production
traffic through this
config today and I ended up with a metric ton of:</div>
<div> 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]</div>

</div>
<div>And, the xlogs from the above line:</div>
<div> Unable to validate dialog, fixing - 3 BYE on
<callid></div>
<div><br>
</div>
<div>It showed up on a number of BYEs and ACKs. My
dialog module
config is as follows:</div>
<div><br>
</div>
<div>
<div># ----- dialog params -----</div>
<div>modparam("dialog", "dlg_flag", 4)</div>
<div>modparam("dialog", "bye_on_timeout_flag", 4)</div>
<div>modparam("dialog", "default_timeout", 21600)</div>
<div>modparam("dialog|sst", "timeout_avp",
"$avp(s:dialog_timeout)")</div>
<div>modparam("dialog", "dlg_extra_hdrs", "Hint:
dialog expired\r\n")</div>
<div>modparam("dialog", "dlg_match_mode", 1) # 0
= DID_ONLY; 1 = DID
first, SIP second; 2 = SIP only</div>
<div>modparam("dialog", "db_url",
"mysql://osuer:ospass@dbcluster/osdb")</div>
<div>modparam("dialog", "table_name", "dialog_1")</div>
<div>modparam("dialog", "db_mode", 1) # 1 =
Realtime to DB; 2 =
delayed; 3 = on shutdown</div>
<div>modparam("dialog", "profiles_with_value",
"711calls; 729calls;
calls")</div>
</div>
<div><br>
</div>
<div>create_dialog() runs on all initial INVITEs.</div>
<div><br>
</div>
<div>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.</div>
<div><br>
</div>
<div>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?</div>
