<br>
How did you get from </tt><tt>opensipsctl to uac_cancel.sh?
Where do you see this (23430) output? Are you sure it is not
used just for debugging? I think it just prints the PID of the
process.<br>

Also when I use exec_msg, the opensips doesn't hang and
looks like it works as expected. Although while using
exec_msg function, it adds an additional parameter when
executing the command at the end in a parentheses. For
eg: my function is:<br>
exec_msg("/usr/local/myOpensips/sbin/opensipsctl fifo
t_uac_cancel $avp(caller_cid) $avp(caller_cseq)");<br>
<br>
</div>
In the debug it shows command executed as:<br>
/usr/local/myOpensips/etc/opensips/uac_cancel.sh
btf4RC2Z8tBlpG6eAG-hZK4cZxENCEud 8222 (23430)<br>
<br>
</div>
I'm not sure what (23430) is in the above command because of
which most likely the t_uac_cancel fails. Because If I run
this command directly it gives me syntax error:<br>
-bash: syntax error near unexpected token `('<br>
<br>
</div>
I dont even have an option to single quote that parameter as
it comes automatically when the function is executed.<br>

<div>Hello Razvan,<br>

I extracted the source
opensips-1.11.2-4c08b62_src.tar.gz created on
Sept 7th and tried again. This time, as soon
as the exec_avp command is fired, the opensips
stops processing anything after that. The
service doesn't even stop when tried to stop
cleanly. It just hangs. After a minute or so,
it shuts down with the following in the logs:<br>

Should I try with an older stable version
instead?? I think there is something wrong with
the way this is going. Let me know if I can be
of any help to troubleshoot this further.<br>

<div>Hello Razvan,<br>
I am running 1.11.2 extracted
from the following source file:<br>
opensips-1.11.2-4fda9a1_src.tar.gz<br>
<br>
</div>
<div>A little more background on
the problem:<br>
</div>
<div>The caller is connected on
TCP and relayed over UDP. The
transaction that I am trying to
cancel is an UDP transaction. I
dont believe this should have
any concern with the problem I'm
facing but still mentioning.
Basically I want to cancel this
transaction, get the caller into
the failure route and relay it
to a different destination !!<br>

<div>Hello,<br>

I try to
cancel a
running
transaction in
opensips based
on certain
conditions.
When I try
this from the
script:<br>
</div>
exec_avp("/usr/local/myOpensips/sbin/opensipsctl
fifo
t_uac_cancel
$avp(caller_cid)
$avp(caller_cseq)",
"$avp(result)");<br>
</div>
<div>The
callid and
cseq is
properly
substituted in
the
appropriate
AVPs.<br>
</div>
I get, **
ERROR: error
opening read
fifo
/tmp/opensips_receiver_24405
in the
resulting AVP.
Whereas when I
run this
command
directly from
my shell it
runs fine and
cancels the
transaction as
expected.<br>
</div>
Tried to
google around
the problem
and couldn't
find much. I
read about
some selinux
thing that
might block
opensips from
executing the
MI command,
but I'm pretty
sure selinux
is disabled on
my machine.
Where else do
I look for a
fix such that
my script is
able to
execute this
!!<br>
<br>
</div>
Thanks in
advance for
any pointers.<br>
