<div>I understand your position. Unfortunately since there are
UAs that do this, and they RFC compliant in their behavior, the
validate_dialog() function is less useful in the real world.
I've had to remove it from my configs.</div>

I agree with you - we like it or not, needs yo comply with the RFC.
<br>
As today we had the monthly IRC meeting, I brought this into
discussion (SIP-wise URI matching) and already have an action plan
set (together with Ovidiu Sas).<br>

<div>I'm fighting a similar situation regarding the behavior of
the uac_replace_from function. It seems that Acme SBCs replace
the value of the From header (old To header) on new requests
within a dialog, and this breaks the uac_replace_from function.
I've cited the second paragraph of section 12.2.1.1 of RFC
3261. The carrier I'm fighting with now reads this "mandatory
reflection" behavior as part of the old RFC 2543, not 3261.
They aren't willing to put any more time into configuring their
Acme to maintain the headers. I work with another carrier
partner who also uses Acme who was able to make the change. I'm
trying to get the details from the second carrier so I can share
them with the first.</div>

Life is complicated with RFCs...even we all read the same papers, we
have as many opinions as number of readers :P.<br>
<br>
BTW, have you tested the ACK patch I sent you ?<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>

<div text="#000000" bgcolor="#ffffff"> 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>

follows:</div>

</div>
<div>
<div># ----- dialog params -----</div>
<div>modparam("dialog", "dlg_flag", 4)</div>
<div>modparam("dialog",

<div>create_dialog() runs on all initial

<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>
