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>
