Hello Guillaume,<br>
<br>
thanks, I will backport. Is this solving the issue reported in this
email thread, or the one related to the drop of another early dialog
is still there?<br>
<br>
Cheers,<br>
Daniel<br>

Hello Guillaume,<br>
<br>
I pushed two commits on master branch:<br>

<br>
The changes restore the previous values for T and T_branch,
should be safer for the case when t_cancel_callid() is used in
the context of another transaction.<br>
<br>
The patches are for master branch, but should apply easily to
4.0 branch. If you confirm they are working fine, then I will
backport to git branch 4.0 as well.<br>
<br>

<br>
Hi Daniel,<br>
<br>
I have tested it on 4.0 branch, and its working fine<br>
<br>

Hi Daniel<br>
<br>
No, replies are not dropped.<br>
<br>
I looked into source code, particularly
tmx_mod.c::t_cancel_callid() function.<br>
It alter the global pointer T (pointing to the transaction
currently processed), but do not restore original value at
the end:<br>
- at the beginning of t_cancel_callid(), T is NULL<br>
- then t_lookup_callid() make it point to the transaction
we want to cancel<br>
- and the pointer is not cleanup before exiting
t_cancel_callid<br>
<br>
Here is a patch that fix this issue (it may not be the
correct way to do it)<br>
<br>
<br>
Regards,<br>
Guillaume<br>

Hello,<br>
<br>
are you dropping replies? I don't see the 'SIP/2.0 487
Request Terminated' being sent to caller, it looks ok and
has two Via headers.<br>

Hi All<br>
<br>
We wan't to prevent our users to make more than one
call at time, so we choose to disconnect the previous
call.<br>
When the previous call is established, we use
dlg_bye(), and its ok.<br>
But when it is in early state, we use
t_cancel_callid() to cancel its INVITE transaction.<br>
<br>
We face 2 issues:<br>
1) we use local-request event route to account
calls on timeout. Sometimes this route is called for
the cancelled call (after default timeout of 1 hour)<br>
</blockquote>
<br>
what is in the local-request in this case? Is it a BYE?<br>
<br>
<blockquote cite="mid:528C93DD.3090509@gmail.com"
type="cite"> 2) t_cancel_callid() cancel previous
call, but also <u>make current dialog disappear</u>:
call is still ongoing and we can answer and talk to
each other, but the dialog does not appear in 'kamctl
stats dialog' and 'kamctl mi dlg_list' commands<br>
<br>
Is there a known limitation, or do we misuse
t_cancel_callid() ?<br>
</blockquote>
Can you send the log with debug=3 in kamailio.cfg? It
will help to see what happens. Otherwise, if the call id
is different for current dialog, it should not happen.
The ngrep output in this situation (for both first and
second invite) will help.<br>
<br>

Hi Daniel,<br>
<br>
local-request is triggered by a BYE<br>
I have attached sample log and trace<br>
<br>
There is some kind of dialogs mixing. Here is the 1st call
dialog as reported by "kamctl mi dlg_list" <u>before and
after</u> the 2d call is answered:<br>
