<p>Hello,</p>
<p>you have to provide the version of kamailio for each reported
kamailio issue, otherwise is hard to match with the source code.
Use 'kamailio -v' to get version details.</p>
<p>Cheers,<br>

<div dir="ltr">Hi,<br>
<br>
<div>Is there a way to broadcast KDMQ to the cluster but not
expect a reply back !?as far as I've read the source code
dmq_bcast_message is exactly like dmq_send_message in a way
that it expects a callback to be executed on response i.e
expects a reply.</div>
<div><br>
</div>
<div>So, the situation I'm facing is I'm broadcasting message to
cluster and I do not want a reply back. The following two
options result in crash & core dump.</div>
<div><br>
</div>
<div>1 - If my script doesn't respond back, by use of
dmq_handle_message, it marks the destined servers as
"inactive" and stops usrloc sync process which
isn't desirable.</div>
<div>2 - If I respond back with the dmq_handle_message it
crashes the Kamailio which just received this broadcasted
message.</div>
<div><br>
</div>
<div>Here is how its done in script:<br>
