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>
<br>
Cheers,<br>
Daniel<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>
