I would suggest reading all that to understand the interaction a bit better. Its not such a simple answer, it depends on the strategy and a number of other factors.<div><div><br></div><div>Mike</div><div><br><div><div>On Jun 12, 2014, at 10:27 AM, Alvaro Mari-Thompson <<a href="mailto:alvaro@voicebooth.com">alvaro@voicebooth.com</a>> wrote:</div><br class="Apple-interchange-newline"><blockquote type="cite"><div lang="EN-GB" link="#0563C1" vlink="#954F72" style="font-family: Helvetica; font-size: 12px; font-style: normal; font-variant: normal; font-weight: normal; letter-spacing: normal; line-height: normal; orphans: auto; text-align: start; text-indent: 0px; text-transform: none; white-space: normal; widows: auto; word-spacing: 0px; -webkit-text-stroke-width: 0px;"><div class="WordSection1" style="page: WordSection1;"><div style="margin: 0cm 0cm 0.0001pt; font-size: 11pt; font-family: Calibri, sans-serif;">Hi all,<o:p></o:p></div><div style="margin: 0cm 0cm 0.0001pt; font-size: 11pt; font-family: Calibri, sans-serif;"><o:p> </o:p></div><div style="margin: 0cm 0cm 0.0001pt; font-size: 11pt; font-family: Calibri, sans-serif;">I’d like to clarify the intended behaviour of a FIFO queue, with regards to the delivery strategy – by default, do FIFO-placed calls ring through to all members of the queue, or do they do it round-robin?<o:p></o:p></div><div style="margin: 0cm 0cm 0.0001pt; font-size: 11pt; font-family: Calibri, sans-serif;"><o:p> </o:p></div><div style="margin: 0cm 0cm 0.0001pt; font-size: 11pt; font-family: Calibri, sans-serif;">I have the following simple configuration:<o:p></o:p></div><div style="margin: 0cm 0cm 0.0001pt; font-size: 11pt; font-family: Calibri, sans-serif;"><o:p> </o:p></div><div style="margin: 0cm 0cm 0.0001pt; font-size: 11pt; font-family: Calibri, sans-serif;"><fifo name="<a href="mailto:2000@sample.com" style="color: rgb(149, 79, 114); text-decoration: underline;">2000@sample.com</a>" importance="0"><o:p></o:p></div><div style="margin: 0cm 0cm 0.0001pt; font-size: 11pt; font-family: Calibri, sans-serif;"> <member timeout="20" simo="1" lag="5">{fifo_member_wait=nowait}<a href="mailto:user/1001@sample.com" style="color: rgb(149, 79, 114); text-decoration: underline;">user/1001@sample.com</a></member><o:p></o:p></div><div style="margin: 0cm 0cm 0.0001pt; font-size: 11pt; font-family: Calibri, sans-serif;"> <member timeout="20" simo="1" lag="5">{fifo_member_wait=nowait}<a href="mailto:user/1002@sample.com" style="color: rgb(149, 79, 114); text-decoration: underline;">user/1002@sample.com</a></member><o:p></o:p></div><div style="margin: 0cm 0cm 0.0001pt; font-size: 11pt; font-family: Calibri, sans-serif;"></fifo><o:p></o:p></div><div style="margin: 0cm 0cm 0.0001pt; font-size: 11pt; font-family: Calibri, sans-serif;"><o:p> </o:p></div><div style="margin: 0cm 0cm 0.0001pt; font-size: 11pt; font-family: Calibri, sans-serif;">The behaviour I’m seeing is this: When I put a call through to the FIFO, it first tries to deliver it to 1001, then 1002, and so on. If I put a call through the first time, it goes to 1001, but if I call again, it starts at 1002.<o:p></o:p></div><div style="margin: 0cm 0cm 0.0001pt; font-size: 11pt; font-family: Calibri, sans-serif;"><o:p> </o:p></div><div style="margin: 0cm 0cm 0.0001pt; font-size: 11pt; font-family: Calibri, sans-serif;">If on the other hand, I put the following in the dialplan:<o:p></o:p></div><div style="margin: 0cm 0cm 0.0001pt; font-size: 11pt; font-family: Calibri, sans-serif;"><o:p> </o:p></div><div style="margin: 0cm 0cm 0.0001pt; font-size: 11pt; font-family: Calibri, sans-serif;"><action application=”set” data=”fifo_destroy_after_use=true” /><o:p></o:p></div><div style="margin: 0cm 0cm 0.0001pt; font-size: 11pt; font-family: Calibri, sans-serif;"><o:p> </o:p></div><div style="margin: 0cm 0cm 0.0001pt; font-size: 11pt; font-family: Calibri, sans-serif;">The first time I place a call, it follows the round-robin behaviour described above, but any subsequent calls get delivered simulatenously to the FIFO members (i.e. 1001 and 1002 ring at the same time until one picks it up).<o:p></o:p></div><div style="margin: 0cm 0cm 0.0001pt; font-size: 11pt; font-family: Calibri, sans-serif;"><o:p> </o:p></div><div style="margin: 0cm 0cm 0.0001pt; font-size: 11pt; font-family: Calibri, sans-serif;">I can’t make head nor tail of how this is supposed to work.
