Hi Anthony, <br><br>Thanks a lot for the solution. I shall try uuid_kill.<br><br>I am currently using "sendmsg" to "hangup" a UUID call, like this:<br><br> snprintf(cmd, sizeof(cmd), "sendmsg %s\ncall-command: hangup\nhangup-cause: ....<br>
<br>I send the message using esl_send_recv() and check handle.last_sr_reply immediately after the function returns. Now I realize this is wrong because "sendmsg" is async and "api uuid_kill" can guarantee a reply. <br>
<br>Thanks again, <br>D.Ma<br><br><div class="gmail_quote">On Thu, Aug 4, 2011 at 12:44 PM, Anthony Minessale <span dir="ltr"><<a href="mailto:anthony.minessale@gmail.com">anthony.minessale@gmail.com</a>></span> wrote:<br>
<blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex;">the events are async so you can't count on the next event returned to<br>
be a reply to one you sent.<br>
you need to use the api command and uuid_kill to do the hangup<br>
<br>
char cmd[128];<br>
snprintf(cmd, sizeof(cmd), "api uuid_kill %s\n\n", some_uuid);<br>
<br>
esl_send_recv(&handle, cmd);<br>
<br>
this function actually guarantees a reply<br>
